RotoFab + VMax Ported 87mm TB For LSA = Tune? - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

I know this has been asked before, but I cannot find anything in my searches.

Do I have to get a tune, or am I ok stock? I thought it was ok without a tune, but I just read some post that stated the opposite.

I have the same setup and I've been running mine for 2300 miles now. Dynoed stock at 505rwhp 496 ft lbs torque. Installed my roto fab cai and ported v max went back to the same dyno and put down 542rwhp and 427 ft lbs torque. No tune. Just wanted to see if it made power stock and checked out ok. And my air fuel mixture was perfect almost and I don't wanna ruin warranty so I left it.

No tuning is needed.

It's not 427ft. lbs. 527 ft. lbs., right?

Ouch, what happened to the TQ?

I am gonna be getting the JDP 625 package soon and it contains a roto fab, vmax and 5% overdrive. They say it does not require a tune so you should be fine.

As long as your A/F ratio was good, then you have nothing to worry about.

You'll be just fine with those modifications and no tuning.

That is correct, our 625 package does not require tuning or fuel accelerator.

Feel free to call, PM or email me anytime with questions.

Best regards,

So if my back of the envelope calculations are correct, that means you are pushing 623hp at the crank.
