I would be careful as well. As mentioned, easy to kill spark plugs Do you have experience tuning? Share your thoughts on how you would do here,...

I guess it would be not a good idea long term… I agree with N2speed

the early days were when race pak was a product, and the company that made that product was named competition systems inc the first year or two,...

The first item on the to-do list is to install the wideband. You say that is done, so next you have to get it to read accurately in the scanner. If...

If you think you can do better then a computer go for it. let us know the long term results in all weather conditions and various loads.

Okay let me get your take on this Bill. Everyone seems to suggest the 12212156 OS. The car is a 99 Firebird LS1. I found a 02 Firebird LS1 with a...

Thanks for the response. The truck was driving with the tune posted above; TUTD was disabled at the time of driving. On my 6L80, D6 is normal drive...

We can use the nv ratio, or estimated gear, for boost by gear.

I am seeing a ton more smoke when warmer ambient temps with every tune. Heres a log and tune. Id be curios if anyone has similar issues.

im running 93 but open to e85 and more timing if its worth the hassle of checking each fill up the ethanol content... i have enought fuel pump and...
