Wondering if someone could review my setup and give a 2nd opinion
engine is stock 99 LS1, pac springs, single gt42 turbo, short 3.5" dump, powerglide, 2 bar SD, 7 psi gate spring, E85, siemens 80lb injectors, referenced regulator, A1000 aeromotive pump
Other than the above completely stock motor
had the opportunity to complete some initial tuning and im running across a few issues
1. picking up 0-1 worth of KR (refer logs) is it possible it's not real knock?, conservative timing, no boost yet and only 4000 rpm, gut feeling is my exhaust might be touching a chassis rail
2. car is missing at around 4000rpm and can't seem to pin point why, doesn't appear the ecu is pulling timing and AFR's are good, would i be on the right track putting in 2 range colder plugs and gaping to 0.8?
with regards to the miss you can hear it in the last 10 seconds of this clip
