PI swap guys...untuned/tuned numbers.

Those who have done the swap what were your dyno or track numbers before and after a tune for the swap?

My numbers were 254hp/280tq tuned. My track times (which I really base how much the PI swap helped me) were 15.0@89 before to 13.7@103.5 after. With slicks or DR's its a low 13 sec car.

thats a nice drop in et's. I haven't been to a dyno or track since my swap but it definately is faster. I've been holding out on the tune until new cams come in. Now i'm waiting for some P&P heads to arrive so i'm expecting a big difference from the 179hp i dyno'd npi many years ago. I'm hoping to add 100rwhp(auto), that would be nive.

I have an 00 with cnc ported heads and cams and made 291rwhp and 306rwtq std and 285rwhp and 301rwtq sae.

No numbers, but hope to go to the dyno this coming week, and if I do I'll post some numbers. However, I was on the road the other day, and raced a 03 gt and wasted him. After the race we talked, he said he had full exhaust, diablo chip, ud pullies, cai and tb. Felt really good to win that race, cause before the swap I was losing to every 99+ gt on the block!
