Taka I agree about ignition being a problem with the 3B. I have Ned's older Stage III setup with 2.5 bar PT. At high boost/heat, I have had a constant problem of the car "backing off". I adjusted the WG to run "only" 20 psi to solve the problem. I just added an MSD and early returns are the problem has gone away, even with turning up the boost. Regards, Jerry 91 200qa
