well, went to the dyno and its about 75' outside... so its a little warmer than last time... but i think it was only 65' that time...

anyway, I let the truck cool for at least 30mins...

put it on the dyno and guess what.... not even a 400hp club member yet.... WTF????

Before the Port,Throttle Body, FTVB and Chip reburn I was 388... now only 397....????

and my boost guage only says 11-12

 

well this rules out the option that im running too rich, because it looks like im about 12.2 - 12.4.... that might even be a little on the lean side right???

so if its not the program... what could be causing a loss of power? why with all the mods I have am I not even at 400hp?? most the port guys are saying nothing but good... even the WES guys.... and why am I only seeing 11-12 boost and not like 14-15??

 

How did they read the A/F ratios
If I were to guess I would say they just stuck a probe in the tail pipe. if so I say your A/F is pretty good.

With only 30 minutes cool down I say you really have a 400 rwhp truck, but the torque looks a little low. I don't know whats going on, stumped.

 

Drop that 75 to 60 = 400 hp

 

ok, so maybe the temp had a little to do with it.... but thats not where im confused...

all the other ported blower people are saying how they are seeing 20-30 rwhp increase and 2-3 on boost...

well im seeing 8hp increase with ported blower, single blade throttle body, ftvb and chip reburn.... and no boost gains....

so what gives??

 

not to mention, i lost about 20 ft torque

 

Scott,

How far are you from San Antonio? We can get together with my tuner and find out what is wrong.

maybe it is the mechanic?

 

i appreciate the offer, but im up near Dallas... im in Arlington... ya know home of the... well nevermind... think of 6 Flags... forget about the Rangers..... lol

 

cant be mechanic... cuz thats me... hahahahh

but seriously...

how can u do an ftvb wrong?

and the throttle body is about as easy as it gets.... i even adjusted the TPS to .983

the blower only goes back on one way.... not like I have it upside down or anything... all hoses are back to original spot... heck, the wont even fit in wrong spot

and Sal did the chip....

so ???? im clueless

 

maybe bad gas?

 

sal is my tuner also

maybe you got a (safe) tune?

 

a buddy was just poking fun at me about my flowmasters.... i know i havent met one person yet who actually had a good thing to say about flowmasters.... but could that actually be the problem??? i doubt it is... but they are next in line to go!!

 

any other ideas on what it COULD be?? iv been searching and seems like others with same mods are putting down 410 - 420... im about 15-20 below that.... not to mention they are about 15boost


any ideas?

 

Do you have an x pipe with the flowmasters?
