I just bought a 1998 B4C cop car Z28. It has 172k miles on it and came with Jethot longtubes and SLP catback, SLP intke lid, Yank SS3600 converter.
It had never been tuned and was way out of whack.
Jeremy squeezed me in between two other tunes today and worked his magic.
Deleting all the codes due to headers, shoring up the tranny tuning for the SS3600, throwing in a dry nitrous timing retard table that automatically pulls timing based on the dry shot, pulled out TQ management, and then squared away drivability and WOT tune.
I picked up about 10 peak rwhp but a TON under the curve. Some rpms over 20 tq and 20 rwhp. Car made 317 all motor unlocked and ~440 rwhp on a small dry shot using the new NX dry MAF setup, unlocked. His dry nitrous retard tune works wonders on juice
But the best thing was all the tranny tuning. On the way home the car performed like a fine tuned machine that was MUCH more of a performance setup. Shifts are now smooth and crisp, kickdown is now the way it should be and lockup is very predictable. Its like a damn new car and a JOY to drive!
This is my first auto with a stall....and I learned that a good tune is paramount with an auto/stalled car. Best money I have spent in while.
Next we will see what 440 rwhp will do at the track with some sticky tires. Maybe jet up o a 150 shot. I have a bit of room on the injector duty cycle...ill take it right to 100%. Id like to get it in the 10s.
