I'm thinking of either the GIAC ECU chip or the Tip chip.

But some recommended Tip chip first.

Those with 2.8/30V do you guys seen any difference in full auto mode? or only in Tip mode?

or should I just go with the ECU chip first?

do the ecu chip first. I had it that way for more than a year. no probs.
