anyone running stock springs with tnt tune? i assume you dont want to run the race tnt on stock springs,but can you set a rpm limit with the race or non race tnts?

 

yeah, i am running the tnt non race. have been since march. and due to the rpm limits and high boost, i got scared enough to go and do springs.

 

Some folks on here have pulled their head long before Smarty or any other rev increasing downloaders and have found their valves have touched the pistons. If you are pulling I would install springs for piece of mind. Anything that worrys me I like to go ahead and change it. Even the non tnt s/ws raise the rpm a bit over stock.

 

I agree my next mod is going to be springs

 

thanks guys, just what i thought id hear. im going to go ahead and do springs as ive got to retorque head 1 more time anyways.
