    Awesome videos Tom. i own a Grand National and was wondering when you are putting up the second part to the wideband wiring install?

      Thank you Mike, I appreciate that and am glad you enjoy them! I have been very busy lately, but hope to put it up in the next couple weeks. If it helps, the wiring on the new Innovate MTX-L is extremely simple. Far, far simpler than their older versions, one of which I have in my Talon. Good luck with your car and good meeting you!

      Hi there Trell!

      It sounds like you’re already most of the way to having a fast street car! I’m not sure what turbo you have, but if you check the turbobuick forums, many folks are having great success with the Precision Turbo billet turbos. I’ve seen some talk about the 6262 or 6266 and it seems really promising. That said, you’ll need the appropriate torque converter. As for the maf, I believe the Fast Xfi can run speed density, which can be a good setup. I don’t have any personal experience with that, so again I’d check the turbobuick forums, where there’s many more experienced folks. Good luck with it and thank you for the support! -Tom

      Hi Jonathan, you’re welcome and I’m glad you enjoyed the videos! I don’t currently plan on removing the turbo, but you never know! I would search the turbobuick forums, I’m sure someone has taken photos of the process. Good luck with your car! -Tom
