One way to fix KR Is to tune it out :P

I was running a little lean on the top end, increased fueling a little and I cut my KR in 1/2....I also changed the usual stuff like removed a good bit of torque management.

I still need to play with the MAF, PE and Timing tables a bit more, but I can already feel a butt-dyno difference.

So for anyone that is wondering if they should get a tuner..go for it. It takes a couple hours of reading to get the basics and the more you research on it, the better you get.

Hans FWI I got together with some of the GTP crowd back home and a guy with the XP cam went from a 13.8 to a 13.2 just by tuning and dropping 2 pulley sizes. The flip side is there was another guy with basically the same car running 1.9 and 3.29s and couldn't break mid 13s. Just some food for thought I am going to stay rockers for now mostly for the stealth factor and the the WTF factor. if I were you I would get a bigger cam. I know another guy up here and he only runs 13.0 with a 100 shot of spray and a stage 3 nitrous blower cam and gen v. But on the other hand he sprayed a 175 shot and ran a 12.1 spinning on DR at the launch and bogging in second when he sprayed so if you want to go fast up here cam and spray seems to be the ticket.

spray is for ricers or strictly track cars...(my opinion)

I'd like to do it with one power adder only.

well I will disagree with you on the nitrous but that is your opinion. honestly I would say turbo would prolly be your best best for those times up here. You won't lose nearly as much as a m90 would lose due to the altitude. just food for thought

And tuning.

Personally if you just want mid-13'* I'd forget about the injectors. Stock holds up just fine. Also I'd go with a cam instead of rockers. You can say you'll stop at mid 13'*, but we won't believe you.

And if nitrous is only for ricers, then there will be two ricers at WCBF next year.
