really???
because last weekend it put down 398rwhp/ 381rwtq
and heres the old chart from C&C before my tune…
381rwtq
My SES light is on…havent scanned it yet it came on the other day. Im worried I might have a broken valve spring. Last night when it was idling the car didnt sound right to me. Seem’s to pull just fine tho. Idk. Heads are coming off it maybe this winter anyways.
