well let me try to explain better

starts up fine, no weird sounds or smell... everything seems fine... then when I drive... still nothing weird as far as sounds, etc

but the pedal is ALOT "heavier".... i know I used to just barley press on the pedal and it would get up and go... now I have to do a full out WOT to really get going.... i know its not right... everyone with ported eatn says they notice something right way... well to be honest, i do notice something... it actually even is worse than before in my opinion... not to mention, only 12 boost... something is wierd!!!

 

also, not only does the pedal feel real 'heavy" and I gotta put pedal to the metal to really get that "seat of the pants" feel.... but when I do get on it... there is like a delay.... when I press WOT it doesnt immediately GO.... i mean obviously I am still moving... but I dont feel that "KICK" right away... there is like a 1-2 second delay before I get that "KICK"

 

Just a thought. Did you check to make sure the throttle linkage is opening the throttle body all the way?

 

Scott -

Sounds like you have throttle body or throttle cable issue here.

Remove the inlet boot off the TB and have someone in the cab floor the truck (engine off). Make sure the throttle blade is fully opening and the cable is not kinked and smooth in its operation. A "heavy pedal" is not normal.

Max I am looking for dyno charts from a blower ported by Wes...not apten....

 

I know this doesn't affect the heavy pedal but maybe the boost problem. Could the boost actuator be hung, stuck or something?


BTW: Just got mine back today. I will have it on tomorrow.

 

Scott, It does seem as though you may have another problem, from the replys i'm seeing, but even if you dont there is not always a seat of the pants differance. Some people on this board have claimed a loss in tq. with a gain in hp. If this is the case, its going to feel a little weaker down low, but pull better up high. Some people have claimed no gains in boost, while others have posted 2psi gains. In the new 5.0 magazine, apten claims NO boost gains, and no need for a reburn. That's on the cobra, but whats the differance as far as boost goes. I think some stories on here are inconsistant. I myself gained 2.5mph in the eighth mile after the port. I havent dynoed my truck since the port, but twisted99, and caseyo2 have. Both of them were very pleased with there results. Also I'm getting a dyno graph from a local guy i did tomorrow. he made 458rwhp with similar mods. That also brings me to the inconsistancy of the dynos across the nation. He said they set there's to match anothers dyno, so who knows. Anyway scott, i hope that the track will tell the differance. For some reason or another these trucks on here are responding differently to the port jobs. I mean from 18rwhp to 40and even 50+rwhp. thats alot of differance. Also some losing torque and some gaining up to 40+ft lbs. I by now way, am trying to get into another porting war. All this just seems weird to me. Good luck scott, and sorry for the long post everybody.

 

Not to say you didnt get a good port job because it sounds to me that something else is wrong but this is the exact reasonI am going with the original,the tried and true 'APTEN" when i do mine.id rather not try and save a $100 or so on a 30k truck........

 

Scott,
Sounds to me like you are low on tranny fluid. You did mention installing a FTVB at the same time, so perhaps you didn't get the tranny fluid refilled to the correct level. You are supposed to check the trans fluid while the truck is running and the trans is warm.
Might be worth a look

 

Just wanted to add that when people first started getting their Lightning blowers ported I remember reading many times there was no gain in boost, but now it seems that 2psi gain or so is the norm. Dont know what changed.. other then a design change which may be the reaosn why there is now a boost increase.

 

I've been told the design change was to strenghten the case by several people from this board. This brings me back to why some people gain boost and some don't. maybe it was because this porting thing hit big during the winter or people were just slapping some 2lb uppers on or something.....

 

This is not so differant than how 10 trucks on the same identical Chip program, with the same identical Mods, will run 10 very differant ways. Some will be safe and powerful, others will need a more aggressive tune to net the same results, and still others will be pinging and detonating and throwing Rods out the side.

Some of us run awesome on TR-6's, mine ran like total Schitt the second I put them in, many others had prob's with them too, yet some love them. Most say a Throttle Body and Plasma Booster are a total waist of money, yet the day I put both Mods in mine,
I immediatly felt a night and day diff. As for the WASP, I can't say enough good about it, it made a def performance increase difference in mine, immeditaly I felt it pulling and pulling like never before.

The point is, each and everyone of us react very diff to the same Mods, it really is very hard to understand sometimes ???
Of course we all understand climates, elevations, octane, and humidity play a huge part, but even two Lightning living next to each other with identical set ups will sometimes run miles apart.

Scott here has a very unique result, very diff from the others,
and even for those that lost a LITTLE torque, they still boast of the Mid/Upper pulling power, man that is where mine comes alive, yet for me I notice no diff on low end power, except maybe it does seem to not develop boost as fast initially, but again like I say, it seems I'm giving it less gas and going faster, so that makes sence. All I need do is go maybe 1/4 throttle, and WAM I got 10 lbs, if I WOT it, I'll bury the needle over in the tach area (and remember, right now the uppers off, running 4lb only)

Scott,
Def check out the entire Throttle/Cable/Pedal/Spring/Bracket
set up. If you remember, while taken mine for the voyage run,
after about 10 WOT blast, I remembered I never tightened up
the bolt holding the bracket that holds the Throttle Cables.
(it was then I stopped the WOT blast and went home and got the rachet out)

 

well guys, i went home last night and i really looked and I cant find anything lose or hanging around... all hoses seem fine, the throttle body spring also seems fine....

iv got another lightning buddy that knows alot more than me said he will stop by my shop today and check it out and see if there is anything I missed...

anyway, im gonna try and get it on a dyno early next week and then send in my chip to PSP to have reburn... then i guess Ill really be able to know for sure whats going on...

i really belive it has to do with my chip program


p.s. got a quick question... will a single blade throttle body make my low end change at all? i mean, mainly what im not liking is how hard i gotta pound on the pedal... isnt that what a throttle body does???? should help that out right?

Yup the single blade throttle body should only help with throttle responce.

Good luck in finding whats wrong, please keep us updated.

 

You should probably get a reburn before you dyno it. If its lean you may burn some plugs up, or something else.
