I just got a new shaner ported and polished throttle body. I was wondering whether or not my car needed to be retuned? My car was tuned last year for my longtubes, intake, exhaust,etc... and hopefully this summer the new trick flows will be in. What should I do? TIA

Wait till you are finished with the heads. No tune necessary now.

Should I just wait and install the TB with the heads? I have the TB in hand now, but the heads will be done probably in July.

I installed a vortex air bridge to replace the stock one after my h/c tune. strapped it to a dyno and what do you know..im running leaner.

Chris re-did my tune and added more fuel and timing bringing it back to 12.9 afr.... Runs awesome!

You wont know for sure unless you check it on a wide band.
