Sorry to hear this news, keep us updated and I'm hoping for the best. I'm sure this is the last thing you wanted to have happen with the little one on the way and all of the other stressfull stuff to worry about.

Hi.

Buh-mer, RP. Hope it all works out for ya.

Quintin was right - you really roll the dice with these injectors.

Honest to God - make makes consider just buying #24 Ford Motorsports injectors & replace them all - Now.

Quintin - any advice on which actual injector brand will not cause a problem ?

Thanks!

Cheers

Point noted Marc, there are plenty of variables like fuel, possible change in climate between different trucks on the dyno, if there were two different dyno operators, flat out two different truck.

HOWEVER, I'd be interested in hearing what Mike has to say about this truck.

What I'm getting at is, sure all those variables do impact power and torque, and sure he is definitely making more power and torque now than before. But the "majority" of trucks running a TP high octane tune, 3.5" AF1, Maggie SIDO are "consistently" running 260 HP and whatever torque (numbers escape me at the minute).

I agree, that all the variables we listed impact power and torque, but 12HP?

That sounds a bit much to be gas quality, change in climate at the same dyno or a two day period. Not to mention, I'd bet they even had the same dyno operator.

I'm sure Mike knows the exact reason that his numbers were different and it's a perfectly logical explanation. It's just too easy to point at gas quality, climate change and things like that without thoroughly looking at all the other possibilities.

Not disagreeing, not agreeing, just providing a different view at the equation.

I am dismissing those numbers due to lack of miles on his engine, I think it's fair to say he will gain another 10hp/10tq over the next 5k to 10k miles as the engine breaks in a bit? Also he had just replaced his MAF so maybe addaptive strategy was still working through that change. What do you think? Does that sound reasonable?

I know where Marc is coming from with his post also... I like him have seen tons of threads get out of control with pepole obsessed with dyno results etc. I'm sure he was just trying to head that off when he saw my post.

Hi. I dunno, Duke.

I think that what works out to ~5% variance is not beyond the realm of possibility. I think that variance exists even in stock form, mass production being what it is....

I'm not sayin', I 'm just sayin' ...

Wow RP...sorry to hear that.

Did you return to stock before taking it to the dealer?

No need to give them a reason to deny the claim.

 

haha, well I know what you're saying.

A 5% variance in stock trim though sounds kind of steep but then again I guess anything is possible and you're most likely right. I'd be interested to see what it looks like after it breaks in a bit.

 

Yeah. Two injectors and a starter. Should be ready to roll tonight pending they get the final testing done on the motor. It's been a ROYAL PITA but, it's coming together.

I'll post my numbers when I'm back in the saddle. 257 RWHP rings a bell... can't recall my top torque.

 

Rockpick, did they mention which two injectors were bad?

How many miles are on your truck?

Thanks

 

Warrantied? Thank god for no hydrolock.

Duke

 

Well that's about as good as can be expected I guess. At least it wasn't serious.

 

Tried to get which injectors -- the writer that I was talking to on the phone didn't know off the top of his head.

All warrantied.

Picking it up shortly (after a 1.5 hour drive one way... probably closer to 2.5 during rush hour now)... I'll report back shortly.

How likely am I to loose my cats after this incident? Sorry, we're very OT here but, this is how the thread has progressed... we'll get back on track shortly.

Good news that it was all warrantied. I'd speak with the service manager about the CATS and explain your concern. See if you can convince them to replace them as an affected part. Worse case if they'll go, it'll most likely happen in the next 20,000 miles which would happen before the 50,000 emissions warranty. But then again, they'll likely complain about the maggie SISO at that point.

Then again the maggie is after the CATS and there argument should be easy to twart. Sorry, I just have had horrible "warranty" discussions with my local Ford service department so I'm jaded to think of worse case scenarios.

Duke

 

Glad to see Rockpick's injector problem (for which there is a well known Ford TSB, gang) worked out and was properly covered by warranty - it had NOTHING to do with his tuning, or his coming here.

By the way - I agree with Marc, stop thinking that all trucks with a certain level of mods must make 260 RWHP - it just isn't' true - period - and NOBODY has dyno'd more of these trucks than we have - nobody.

The truth is, there is an easy 20 HP variance from weakest to strongest in STOCK trim - we have seen 198 to 219 RWHP in stock trim on bone stock 5.4 3V's - there is no rhyme or reason in those cases, they simply vary - and by the way, yes, fuel quality alone CAN make a 10+ HP difference, we have seen those things happen as well.

It's best not to make proclamations when you do not have the experience of tuning & dyno'ing thousands of these trucks, as without that experience, you just don't have the knowledge - that's not an insult by any means! I mean that in the same way that I have no idea how to do what most of you guys do for a living, and if I had to try, I'd probably starve!

Just some brief info for you - a good time was had by all, & thanks to everyone who made the trip!

 

It sounds like it was a good time, when is the next one? I wanna get up there and meet some guys, and make sure I can get that day off of work.
