Hi, This is my first post so sorry if it is in the wrong place.
The car is a Volvo 740 with Megasquirt 2 v3.
Engine: b230ft with
90+ turbo manifold
ebay t3t4 turbo
Kl racing t2 cam
stock compression ratio 8.7:1
bigger intercooler
1226cc injectors
3 inch exhaust with one muffler and 200 cell cat
95 oktan for winter and E85 for summer.
The problem i'am having is that when cursing down hill lightly pushing the throttle the engine misfires or something. I have tried adding and retarding timing noting seems to help. At around 40-20 kpa. AFR, VE and ignition tables
