Been a few weeks since turbo swap and need more advice now.

Car specs:

Standard map (for now)

GT17/52 turbo

2.25" or 2.5" decat pipe (can't remember)

Uprated seat sport fmic and airtec pipework

EGR and cooler deleted

My problem is its a bit laggy til 2500rpm (understanding been 2200rpm) then it overboosts to 1.6bar when requesting 1.35bar in stock map and still overboosts to redline. Also when I get has high as say 4200rpm there is rumble from engine which is weird.

I've attached the logs Ive done.

Actuator test coming out about 110mbar difference using vcds and actuator is 75% at 4000RPM ish.

3rd gear WOT boost log.xls

actuator test.CSV

Lag will improve a bit when mapped properly and the overboost will be cured by lengthening actuator rod, give it 2 turns and log again. If you have vacuum tester, check at what pressure the rod hits the stop screw.
