Here's 2 third gear pulls from today. I don't know what it is it just feels week, I can't really give it any timing without knock so I pulled it back abit. Trying to prepare car for March 10th races. The biggest diffrence will be running 110 race gas rather then the crappy 92 oct we have on island. Any advice or suggestions would be great. Thanks guys

Boost leak test? Check compression? Check shaft play on turbo.. BOOST LEAK TEST! Check spark plugs, check gap, check plug wires. Report back.

Thanks but all that stuffs good it's just in the tune bro. Race gas at the track and soon a meth injection kit will fix the probs.
