you probably have a base map and running your car on a basemap isnt the best thing. its gonna be rich because thats what a basemap does, its probably hesitates cause of turbo lag or too much fuel, and theres probably too much fuel at start up as well. i wouldnt have wasted my money on those plugs. 2 step colder ngks do the job just fine. my suggestion is to get the thing tuned

 

beleive it or not but since I fixed that exhaust leak on my down pipe my cars been running fine so far.hope fully that was the problem.fingers crossed.
good job with my p75 projkteg no cels at all and its every thing you said.shift light is neat.thanks every body and if the car starts to ---- up again I le t yall know
peace.

 

Hehe yeah. I used to use them until one day I went to fire the ride up and pure gas was shooting out my tailpipe and I stalled out in the middle of nowhere. I couldn't keep the engine running unless I full throttled it. Sadly I drove the car back home that way and determined the fuel modifyers were the culprit :P

 

try giving it 1/4-1/2 throttle and hold the throttle there while starting. since the afr is rich it needs more air during start up.
