Too Rich?

[Jay777]

just got a full 3" turbo back exhaust installed to my R34. Runs a little sluggish in low rev range and when i floor it, it backfires in beginning. Mid and high range it runs good. rest of car is stock.

1. Anyone else experience this after install?

2. Exhaust place said it is running rich, is this so?

3. Should i buy a piggyback computer? Apexi SAFC?

Thanks for any help.

Reset the ECU, worked for me

What he said.

If your not planning on modding it any further then a SAFC could be a go-er. Should get a bit more power and good midrange, and lets not forget economy

Im pretty much at the performance mods limit on my R33 with the stock turbo. And im not planning on going any further unless she blows. So i just bought an SAFC2 and will get that tuned.

resetting works, but when I got an S-AFCII put in, I really felt a difference. My advice is go the piggyback.

thanks guys

yeah i might go the piggyback route. want to install aftermarket cooler as well. should i get the tune after that or tune it now and then install cooler later.?

[Jay777]

also how do i reset the ecu?. Might be a little while till i get the piggyback so might as well reset now and then do a tune later.
