This one is just way behind on what I have now. I need a custom tune....not just an off the shelf PCM. I'm having too many problems with fueling on this PCM ever since ive done the Gen V. Got a drilled 160 in her now...and at night when its cool it runs just above 160...but day when its in the high 70's low 80's it runs at 185....so i obviously need my fans tuned to run w/ the 160. I was scanning tonite...and took off from a light nice and easy roling into it faster and faster to WOT...no knock at all....til just afer i hit 2nd gear....i feel the car lag.....look at my monitor and im seeing 11*KR for a second.....i need something done.

What do you guys recomend? I have heard good things about overkill....cause you can tell him every one of yer mods and he can make a custom tune....only problem is if i wanna tweek something later down the road i cant..i'd have to send it back to him... and i'd be out a car for a week+. Those of you w/ ZZP PCM's......how are they? can they make a custom tune to yer mods?

Is there anyone in Florida or close to Florida who can tune? I have a Powrtuner....but i am too scared to try to write my PCM w/ it cause my laptop is 7 yrs old....and ive heard horror stories about blue screening with older laptops..... and i cannot afford that rite now.... my GTP is my only car now. Not to mension ive read thru all the tuning notebooks and sites.... and its all a foreign language to me.... i just do not get it.
