Holy mother of large type Batman!

Welcome to the forum tuning will give you a ~35hp boost over stock. Go to the track and tell us what you ran before/after the tune!

 

Damn, is this thread meant for the vision impaired?

 

Whos Whatley?

 

will do, with my cortex i had a 13 hp gain and bout 20 tq gain and i knw ive seen you traver1t say get rid of you hand held programer and get a custom tune so thats exactly wut ima do.and b4 i was doin like low 15's wit the cortex so im hopin to gain like half or a whole second

 

my bad dat was a type o i meant wheatley

 

um quik question wuts the difference from a single tune and dual tune i notice you had it on your signature outlawz2004

 

there's not much chance that you will drop a full second, that would be like a 100hp gain but maybe drop .3 seconds just tuning alone.

 

sounds good enough for me. by the way traver1t thats one bad truk you have their

 

dual tune is where the tuner tunes both octane tables(high/low).for example 87/89 tune or 89/91 or 89/93.id just stick with the highest octane.there's not much gain from an 87 tune IMO.
