(every question I have been PM'd has an answer listed in link above)
I dropped 381 off to a friend of mine, Dr.Mario a month or so ago for some work. With exception of my bottom end, all the work was done at my home garage in CT. Mario is the one who built my motor.
Anywho, I had him fab up new i/c pipes along with a list of other small items.
Yesterday I was in CT and went to the shop at 8am to start street tuning. Mario had already found a good MAP with no MIL's and had idle dialed. We just needed to head out for mid and full throttle pulls.
FIRST REACTION=AWESOME!
The biggest difference I found was in the off throttle, 2nd gear pull in such as a parking lot. Coming off the throttle 100% and getting back on it at slow speeds was noticably smoother. Zero bucking that I had gotten so used to! Idle is awesome with the exception of 3 idle stalls in 120miles. I know Evo's still have the same issues but it is 300x's improved compared to my EPROM and we looged it for correction!!!!(ONLY IN REVERSE WITH WHEEL TURNED SO MAY BE RELATED TO THE POWERSTEERING) Basically, you can instantly tell the processing speed is this generation!!!!!
So far, so good! The timing and fuel map corrections were spot on! MAF correction was at -1 which made things easy.
I couldnt get over 17psi so we tested the actuator and found a vacuum leak. New one ordered and we shall continue on next Sunday.
Stay tuned for an update next w/e!
