Pull the 4* and make a pass. If it feels clean stay in it. Pull a plug after the pass, Plugs never tell a lie they are like a window to your motors soul. Give us a shout if you have any more questions. Sounds like you are having some fun with your TMS motor, But with more nitrous you can only have more fun.

 

Thanks man! All things being equal I definitely like this setup much better than the LS1! As always I'll keep you guys posted

 

Well all I can say is that any tuner who pulls a bunch of timing n/a to make the nitrous hit more tolerable is a horrible tuner! Especially when he has the software to make a dual purpose tune. Vector never once told me they were going to tune my car like this and that is shady to say the least! I will NEVER recommend these guys again!!
