sorry guys, i have been sorta busy trying to get rid of knock retard in my car.
yes the shift plus is worth the bux.it works very well. and a very easy install too.
go to my link at car domain. i made a pass this past weekend. had a 2.12 60' time and was on the brakes hard from 1000' on trying not to break out and had a 15.59. and still had 19 degrees of knock retard. i was using race fuel and got rid of some. i called ngk tonight. the told me that when i race, to close my gap up to .040" because with the high boost pressure, it might be blowing the spark out with a .060" gap and causing a knock signal. also i have a ZZP mini afc coming this week to calibrate the maf and richen it up a little. ill post my slips sunday. i really think ill be deep in the 14'* after the run i made sunday
