Are thes the same turbotweak sells ?
Any chips available for the 50's?
Do the 80's need a modded computer?
I bought a set of 80s from Ivan and run E85, and the driveability with these are just like stock. Definitely get the chip from Eric at Turbo Tweak to match your setup. Thanks again Ivan!
Well, I have an exhaust leak that is causing boost not to go past 15# and it is being difficult to locateGlad you like them ... It's a great combination that has been proven to work from 10's to 12's ...
They aren't even the same cars when you run them on E85 and higher boost !!! Lots of fun !
