Hello,

I have a 03' with Greddy Turbo kit, along with emanage running 8psi, upgraded fuel pump, RC 550 injectors, Full exhaust, test pipe.

Sometimes while driving in 3rd around 4000rpm or even down shifting to 2nd id floor it and all i hear it the turbo spooling loud but the car dosent kick but rather hesitate, feels like i got like 50hp lol, then it punches after a few seconds. I look at the AFR gauge and it dips to about 10. It does this for about a few seconds then the car starts to go. usually it stays steady between 11-12 at WOT when it seems to be running normal. Im leaning out for that split second, how bad is that?

What do you guys think?

 

Did u had it tuned? Why on earth didnt you installed the fuel pump that came with the kit.. Do you even have the rc550's installed?

More info please! Im also running the greddy kit at 7.5psi with 3" exhaust.. perhaps move this to the forced induction section?

 

Oooops !! lol, I didnt realize i did have the upgraded fuel pump installed along with the rc550 and yes i did had it previously tuned it was running perfect up untill about 4 days ago !!

How are you liking your set up?

Basically i have everything bolted on that came off the greddy kit !

How do i move this thread? ill just repost it?

 

Moderators need to move it..

Perhaps you could have a leak somewhere, double check the clamps on the piping, make sure they are TIGHT!

Im loving the kit, 296crank hp at 7.5lbs... Thats already 70hp over stock on average ap1 readings... Not to mention the HUGE doubled midrange power! Now waiting on a 11psi tune..

 

If your gauge is reading 10.0 it's probably pegged rich (not lean).
Any big weather changes?
Are you reaching target boost?
I'm not sure how the e-manage maps look but the fueling should be proportional to the boost level: i.e. your car should progressively richen up as your boost pressure rises.
Do they have tip-in/accel enrichment tables?
