To make it easier for you I would always take it back to the shop that did the original tune as I have seen way to many issues on my350z when you take it to another shop first.

 

FWIW I do start to knock at around 11.6-11.7 on a 93 octane gas. 11.5 at peak power is a little lean on 91 octane IMHO. It's either you have to pull more timing or run richer for extra safety. The $500 is a Full Tune and I think it is around $250 for every additional map GTM charges.

 

i just called GTM. they told me that if it is not something major they should be able to clear up the minor problem no charges.

 

Its the tune foresure. I had the same problem where the car lagged between shifts, after I had it tuned I am back to chirping 3rd gear running 285/30/20 in the rear.

 

It's not hard to get ahold of Sam, he is always working late hours..lol, I'll be heading back down in December.

 

What up B? hows the cars? I went to the next level I got tired of the 400rwhp


But ya Sam should clear it up no problem he knows his stuff.... sounds like just a fuel and timing issuse like I said before.

 

thanks guys. ill tell u guys how it goes. ill probably go next week before turkey day. thanks for the input
