The precision turbo has a deffinate affect on the power. On my setup with a factory turbo I could get about 25lb boost with spikes to 27-28. And the boost would drop off shortly after 6000 rpm. With the precision I would get 27-28 lb boost with spikes at or above 30 lbs. and little to no drop off in boost at 6000 rpm or up.

 

What precision turbo was it?

Did it bolt on like the stock K04?

 

It's a K04 turbo off of a Cobalt SS. I sent it in to precision to get the intake bored out and a larger wheel installed. That was $1200.00.

 

Aaaaaaaaaah
