Has anyone recv'd and tried the QC 93 octane tune?
WOT said:Got mine and tried the 93 octane tune. I coudn't go past 3/4 throttle without it detonating like crazy. The motor rattled so loud that it sounded like my motor was full of rocks, but I don't have my 170 'stat in yet. So, I put the 91 octane tune in. It works fine with that tune. I only run 93 octane gas. I guess these motors are pretty temperature sensitive. As soon as I get the thermostat, I'll try the 93 octane tune. The 91 is way better than the stock tune though.

I am sure Marty will get back with you soon.

I have to shift it into second like I have a clutch????? (I have a QC) I thought you could program the transmission to shift at specific RPMs. Then in the 3-4 shift it shifts way early and kind of lays down. Acts like a diesel when they de-accelerate to shift. It shifts around 5500???? I wrote another e-mail to Marty about it but no response yet.
Then when I changed plugs yesterday I noticed some shiny little speckles on one of the plugs. I hope that does not mean problems are on the way. I have only drove it around a 150 miles total since the tune. Then only really got on it from a complete stop about 4 times.
I am beginning to be a little nervous about this SCT buy also.
