I have an 06, stage 2 (3.1 pulley, 60# injectors, injen cai) went to do a pull yesterday and once I hit 5500 rpm in 1st gear it felt like all my power was gone and someone cut the engine, shifted to 2nd and it does the exact same thing at 5000 rpm. Tried it again today and does the same thing. Boost runs up to about 12ish psi but i have no power at all. Any suggestions or help?? Thanks guys.

 

Bump

 

Maybe spark blowout. Check your plugs.

Should be running around a 0.035" gap for S2. Any larger and u can see spark blowout at wot.
