I got a 01 camaro ss,torquer v2 cam,full bolt ons,ported 243 heads stage 2,and a frost tune,car ran fine,i took the ls6 intake off and put a fast 102 and a92mm t/b and a vmax vring,when I start car the idle goes up and down,up and down,i have took intake off 5 times,i know that I dont have a leak,t/b gasket is good,what else could it be

 

switching from a ls6 to fast 102 is a big air diffrence... should get a tune on since the new intake...
