Rusty, I'm not familar with your engine, but a gt2510 will run out of breath at high rpm, gt2530 will be better suit.... one of this is the HKS turbo built by garrett.... the other is a Syivia's turbo....
emanage works by altering the parameters to the stock ecu... if done properly, it will work like charm... the problem is, if it's altered out of the acceptable parameters set in the stock ecu, then the ecu will make changes to counter it... it gets it's signal from MAF, O2, knock sensors etc..... so if you run it too rich/lean in open circuit, then counter measures such as adding/substracting fuel and ignition timming will take place and hence 'revert' back to stock setting...... but, in close circuit, the ecu will have no feedback from the O2 sensor and will not counter your tuning.... so the key is not to tune it out of the acceptable tolerence in open circuit....
Power FC is almost like stock ecu when it comes to electronic controls.... some minor differences only.... main thing that I noticed=radiator fan kicks in at full blast at 94 degree instead of stock setting of 97. no auto timming retard vs knocking. no counter measures if something goes awry..... it basically does what you tell it to do...... so it's all in the tuning....
