I'm trying to decrease a slight to moderate knock retard issue. So, I was hoping we could brainstorm up all the possible sources of true and fake knock signal in an effort to come up with a comprehensive list for the board... I'll get us started: low octane fuel, excessively aggressive...

Ever since I converted to pte 52 kit, 50#er's, 3 bar, 2nd fuel pump, PL chip I've had a part throttle undulation or flutter. Runs great off boost and w/ application of heavy throttle...but wants to undulate or flutter if I use part throttle or if I use heavy throttle and then let off a bit...

help, no reverse and it revs way over red line in each fwd gear...everthing was fine and then I went to pull out hard once(med to med/hvy throttle) and it revved way hi and then clunked into 2nd.....what do you think is up? Thanx, Matt

Truck is running great...but I'd like to lean out the rich idle...We are going to die of carbon monoxide and/or lead poisoning here...suggestions? Titer gapped plugs seemed to help a little (took me from 900 to 800mv at idle) other ideas? I'm afriad to back off fuel pressure with this...

Please tell me who does a good job rebuiling oem turbo at reasonable price??? Matt

Why do I get no fuel cut? I get 16-18 psi steady on the analog boost gage....while the stock boost gage(Map signal right!??) is looking like 14.(see diacom note below..map is getting full signal/max)... and I can hang there for 5 sec or more and never get fuel cut. I think I have the stock...
