PI and Tune?

[5.Woahhh]

If I do a complete PI swap on a 96 will the car need a tune afterwards or will it run just fine?

To get the absolute best results, yes you will need a dyno tune.

for the car to run fine, you will not need a tune. just to get the best power results you would

before pi swap: 15.3 in the 1/4
after pi swap: 15.0 in the 1/4
after tune/h pipe 14.4 in the 1/4

Honestly, it make sense to get a tune. You are raising the compression to 10.5:1 and have to run 93 octane. I was told I didn't have to either, but my car didn't run that great after it.

Yea, get a tune

didn't run great? explain..

He means that if he didnt run 93 octane the car wouldn't run very well. ^^^

I noticed that too after the pi swap, the car was harder to start if I put regular in.

ide recomend a tune, and an adjustment to your air fuel ratio if you need it.

You raised the compression, thus requiring more octane.
