Hi all

I just replaced the original cam in my 2002 z06 corvette LS6 engine with a custom cam and had the throttle body ported.

Car has LG super pro long tube headers, blueprinted heads and halltech cold air intake. Car was producing around 400hp before cam and throttle body upgrade and was tuned for 104 sunoco fuel.

After starting up perfectly the first couple of times it now has a hard time starting as if it has no fuel (yes, we checked and it has fuel).

Once it starts it maintain the idle but if I rev up it shuts off when coming down in RPM.

Will the ECU reprogram itself and adapt to the new upgrade by driving the car around or will it be necessary to re-tune?

If re-tune is necessary, can anyone give me some tips on where to start in terms of re-tuning the car?

I have some dyno time on wednesday and would like to have an idea where to start.

These are the new cam specs:

232-240 duration
0.598 intake lift
0.600 exhaust lift
112 LSA

Also upgraded to Comp 921 dual springs, spring seats, seals, Ti retainers and pushrods.

Thanks in advance.
