Description
Stage 2 (TUNE PORT INJECTION) chip for TPI vehicles with STOCK heads and cam upgrades. There are 3 levels depending on camshaft.
Level1 is for the stock camshaft.
Level2 is for 210 duration camshafts
Level3 is for 218-222 duration camshaft. You really shouldnt run this much camshaft with a TPI intake. You really need a RAM intake whether a TPIS miniram which is hard to come by, Holley/Weiand Stealth ram or Edelbrock Pro Flo XT intake. This is also the max cam I recommend using with GM heads. Changing heads = custom chip.
