share the info...

what did you have done...

slicks, chip, DP, cold air, adj. wastegate?

oh boy now I have to let out my secrets

3" downpipe, 110 race chip, 110 leaded race gas, 26x8.5 slicks, cold air kit, stock intercooler cleaned out, rjc powerplate, walbro 340 and hotwire, adj. fuel pressure reg, stock injectors cleaned, stock turbo...boost set at 23 psi and 45 degree outside temps

doesn't take much to bust off low to mid 12's on a Buick that's for sure

good to hear... i just need to get some tires and a good chip/gas then maybe i can play... my car never wants to perform to its full potential... prolly just needs a good tuning... thanks for the info and letting out your secrets
