Well finally got to do some reading on the truck and have a few questions
What should the long term fuel trim be at idle ?
what should it be with an ATI procharger ?
after a few blasts we figured out there is no Knock retard whatsoever at any RPM intake temps read at 105 quite low my tuner buddy said
i think my tranny problems of late are computer induced i got him to read the crank sensor and tell me what horsepower it was seeing 395hp
what happens the truck pulls all the way up to the shift pioint then bangs of the rev limiter and doesn't shift Severve TQM?
also anyone with an ATI kit with stock injectors
what is your idle fuel PSI
My favourite part of the nite quote "i think we can see at least 30-50hp outta this baby with some tuning" <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
anyhow sorry for the words
Jim

 

is your maf before or after the blower? on a whipple set up the maf is before the whipple and the IAT sensor is part of the MAF so it doesn't read the true IAT.

30-50hp! <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

 

My MAF is after the blower almost the stock postion
after the intercooler you know the thing that whipples don't have <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

jim if your tranny banks rev limiter likwe you explained in you message it sounds like your clutches packets are going. Do you think its wise to run your MAF After the s/c I dont think the MAF can work properly with 9 or 10PSI passing passed it. I spoke to some guys @ ASM and Magnacharger and asked about that last week while contemplating the inter cooler design, they both claim that the air passing by a MAF at that speed and pressure is not good. They both claim that it cant sense the amount of air passing by it, and some other ****.
Thanks for the pics

well After figuring out a few problems out my truck has never run better except for the tranny and the lack of fuel <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
It idles nice and smooth has a a lot more power not that i figured out why half the engine was running all screwed up
Damn A/f Guage from autometer screwed up the bank 1 02 sensor
The guy that is tuning my truck says it's running really good we've been out three nites just to get a feel for how the truck is running and to fix a few issues and to figure out what the next steps need to be
Bigger injectors and a new tranny
and then a smaller pulley <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" />
Keep you guys posted
Jim

 

What injectors are you running now? What injectors are you goin to? Which tranny are you running

 

I'm running the stock injectors which aren't enough for anything
Also gettin a built tranny from a guy here in toronto It's gonna have all the goodies hardended parts and billet servo basically the all the best stuff o available
I'm gettting the same injectors parish has 41Lber's and hope i have enough fuel to keep me going through the mods.. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
