HI guys i just got a 1994 trans am GT and man shes sweet, i just installed a new (fuel injection performance Kit)...comes with a KnK air filter and i put in a new series 40 flowmaster mofler,to be honest my car has picked up some extra HP cuss i can feel it ,duno how much cuss i have not taken her to the DYNO yet.

My question is simple, should i install a hypertec (power pogramer 3) first or a LT4 intake ......is about 250 bucks not bad
how much HP gain can i spect from a LT4 intake for my stock LT1 intake ?????????.

and yes how much HP gain from a hypertec chip??????????.

 

The Hypertech isnt really that good. Get a custom tune from someone.

 

I believe that the LT4 intake wont fit w/o LT4 heads. Might be wrong but Id find out. The PP3 is not that good of a tuner from what most people say. I did my pulley at the same time so Im not sure what it would have done alone...Welcome and mail any questions there are guys on here that REALLY know their stuff. Unfortunately I aint one of em
