At 5000rpm im starving for fuel it becomes lean because of the cold air intake and the 75mm throttle body. I have the hypertech programer,what should i do.
I also have; xpipe w/hi flow cats
flowmaster
headers
4:10 gears
msd ignition
lambo doors& more

 

There's no way you should be going lean with those mods, unless the tune is bad. Was it a canned tune from the manufacturer of the programmer?

 

Yeah not a chance ur running lean. I have the stock injectors and i dont run lean. Even with a bad tune i would highly doubt you would come even close to running lean. Maybe your fuel pump is not running at full capacity

 

i hade it dyno they said at 4500 its starving for fuel my tune is a programmer

 

i hade it dyno, my tune is a programmer.


That confuses me, I really dont understand what you're trying to say.

 

just go in and adjust the a/f ratio with your hypertech, I've never seen that kind of a handheld tuner before but an xcal2 allows ya to do it.

 

How about changing the fuel filter?
