I have an AVC-R... it's not my favorite boost controller in the world... but it works fine for me right now as I don't have any problems controlling boost with my setup (2.4 + 35R). Since I finished the project, I've broken three transfer cases, and have only been able to pull off one night where we did 3 passes (11, 11, 10.9)... with 1.9 and high 1.8 60 fts.

Right now I have a Kaaz front and center diff on order so hopefully that will help my transfer case issues.

But I've been thinking of how to a) improve the time and b) to improve reliability. The first thing I've thought of is running lower boost in 1st and 2nd gear. We burned a ton of tire in both these gears... and I think the lower boost in these gears might help with the wheel spin.

So off the top of my head, I thought the best way to set this up is to setup one of the outputs on my Autronic to trip a relay to the boost controller solenoid once a certain vehicle speed is reached. Do you guys think this will work? Anyone done this before?

Also, I need to figure out how to make the launch control give a better 60 ft, but still be as gentle as possible on the drivetrain. For the one night (3 passes) we did not have a diff failure, I had it set at 5k rpm, no ignition retard, and turn off at 5 kph. This worked well and the car eased out of a standstill, then after traveling a few feet the launch control would turn off and boom the tires would break loose. I'm thinking of leaving the launch control on for longer. Is anyone using the launch control to keep the revs down for longer than the first few feet out of the hole? By keeping the revs down you could perhaps limit wheelspin?
