Message Hi guys!

When mashing my foot to the floor (running stock boost without safety boost solenoids) it pulls hard but hesitates around 3500RPM.

I've been having a problem setting the timing properly, i have 3 CAS units, my original CAS was idling @ 40 degrees so i swapped for another and the other 2 can only go down to 17 degrees when turned fully counter clockwise.

I have 3 CAS units & find it hard to believe they are all faulty (one was running fine when removed from another car), a manual conversion with the neutral switch not wired up & an eprom tune. Conzult says the base timing is 15 degrees @ idle.

The car was running fine a few days ago even with this timing problem.
