I have had my car fitted with a maptun stage 1.
First at high revs/high gear the power was fluctuating quite a bit. Between 1 and 1,4 bar.
This was adressed to a faulty wastegate actuator.
Yesterday we put a stronger actuator in (for 0.6 bar). This caused a new problem. The car is now building up to much pressure which makes it end up in an occasional fuel cut. This is especially the case coming out of very low revs and WOT.
I am using 98 octane fuel and this is what we already changed:
- soleniod valve and hoses
- wastegate actuator (now an uprated model for 0,6 bar)
- map sensor and hose
- maptun software (tried 1 other computer, both give in another car steady 1,1 bar pressure)
- dumpvalve
- di-cassette
I'm out idea's .....anybody else got a clue
