FAST to LS6 Intake Swap, tune ????
I recently bought another camaro as a DD. Well the car I bought has a Fast 90/90 setup and my car I run at the track(car in my sig) still has a stock LS6 with stock ported TB. Both cars have recently been tuned so I have a good bit of money tied up in each tuning wise...
My question is this: Can I swap just intakes without having to retune both cars? I am not touching the injectors, just intake and TB.
FYI - Looking back i wish i had waited to get my new DD tuned but at the time I wasn't wanting to go any faster in my silver car. Then after watching a few races and reading a few new articles I now want to go 9.6 or better. Hind sight is always 20/20....
Thanks in advance!

It will affect your AFR's if you swap intakes - mostly in the upper RPM regions I believe (where the FAST shines over the LS6). That, and I think some tuners add timing in down low for the FAST intakes, which may be a bit much for an LS6 intake.
You can make the swap and observe the changes on a WBO2 and a scanner (to look for KR) to see what the effect is for free (assuming you or a friend has a WBO2 & scanner handy). But, I'm willing to bet there's going to be a bit of a difference. Either way, a tuner usually won't charge the full amount to retune for a minor change like that - especially if you're not hoping back on the dyno.

Thanks for the reply. I tune myself with EFI live but just on the nitrous side. I have the scan tool with EFI live so I can scan for KR but no WB. However I do have a good relationship with my tuner so maybe I won't be too much. I think I'm going to make the swap either way because I really think my LS6 intake is becoming a bottleneck above a 250 shot.
