#5951, "Clutch is slipping maybe?? Could it be something else?"
Ok, I thik I got my 660's tuned pretty close. But when im doing 3rd gear pulls to get them tuned my car feels like Im fluttering the gas. I dont know if its the clutch or what. The car doesnt feel any faster than it did with the stock 450's in it. It pulls but not very hard... Thats why im wondering if it could be the clutch slipping under full boost. Im guessing its still the stock clutch with 125k miles on it. Any way to figure out if its slipping? Could it be because im not running an AFPR?? Im not sure how the AFPR's work so fill me in if thats a dumb thing to say lol...

try sitting in your driveway in 1st gear and letting out the clutch very slowly and if you can let off the clutch completley or it's way off the floor your clutch is probably about to go. and i think i know the feeling your talking about. sort of like a hesitation i think? could be your plugs or wires or you could have a leak somwhere that you don't feel under low boost but you can feel while boosting high.

Its not really a hesitation. It does it at WOT under full boost. Almost like youre moving the gas pedal up and down. but you can only slightly feel it. Ill go tighten up my connectors for my FMIC, maybe i have a boost leak idk...

if you push the gas pedal down to WOT and then to half, do the RPM's shoot up noticibly faster/slower w/o much pull? if so then its the clutch...
i.e. your RPMs fly up but the car doens't seem proportionately faster-- also check the wires, but I doubt its the stock clutch at 125k, but it could most definitely be OEM

Ive got an AFC It could just be my tuning... Its the first time Ive tuned anything... What do you mean I could have pulled too much fuel out? Does running lean cause what im describing? Im not getting knock and my 02's are at like .90

I wouldn't think so. If you were running lean you would have knock and then get fuel cut. Mine has done it very minorly and if feels liek the clutch is slipping, but I've never had a logger to see if I'm getting any knock. Good luck man.

I have had my car have a slight hesitation or lack of acceleration where it felt like the clutch kind of gave way and the car jerked a little bit, but I have concluded with a significant amount of belief it was fuel cut from running too lean.

Fuel cut is to much fuel, not too little. When too much fuel is in the mix, the ECU stops delivery and you hit fuel cut. Too lean means you have timing pulled by the ECU and there is a noticable decrease in performance (and also engine danger).
