But I assure you, once V2.1 is out to the public you will be very impressed with the response.
Sorry, I just don't see how can any tune can reduce the turbo lag. Like mentioned before,running a higher boost would induce more lag, correct?
Maybe throttle response is improved? The lag on this car is minimal at any rate.

yes this is true to a point.. you get turbo lag with more boost forsay but with the little turbos we are useing in these cars there really 0 to no lag. im 100% stock and i feel little if any lag. im not sure how the tune work cause i dont have one yet, but i cant see laging to bad even tho you up the boost. the turbo and the compressure size is what makes lag boost just helps it lag more .
this is why NOS was made use a 50shot into the intercooler or intake and u will be lag free

im looking at the jb2 myself and X for 16psi im looking and im likeing what i see. just getting more info on it before i buy.

thanks

If you want lag-less tune, remove your turbos.

Yeah, what they said. My EVO had tons of lag. The 335i did not. The Porsche was in between.

IMO, I would always prefer a turbocharged car to a NA car, despite the lag. I say that, and I have a NA car at this time. It just has the torque available at lower RPMs.

Can't wait to turbocharge the vette.

Procede is lagless, but I'm having an issue with my ECU

I will say, Active Autowerkes with the Exhaust is probably the best tune if you don't know how to work on cars. you get 420 hp just bolting that on with 91 octane.

Absolutely more noticeable lag. Even Jeff@Eurobahn mentioned that there would be more, "perceived" lag from installing the SSTT. This is where SSTT stage 2 comes in. We will see what it really does upon release.
I would really like to drive a JBX equipped car though. Very interesting indeed.
