with just a chip you are still limited to about 10 psi for safety, beyond that no one can say if you will be safe or not. figure about 225whp with that setup.
don't think that by upping the injectors that you can max out the system safely with just a chip that removes fuel cut and remaps the stock fuel maps to allow for the larger injectors. after about 11-12psi the stock timing and fuel maps are not safe.

With an adjustable FPR and 40-43 psi base pressure the fuel maps actually aren't that bad, but the timing is attrocious. Something like 34* advance has been observed above 10 psi on the stock computer. Don't risk it.
Additionally past 11-12psi the stock turbo is pumping increasingly hotter air which further compounds the timing problem. Add to that the fact that most older engines have carbon deposits which act like diesel glow plugs and BOOM is imminent.

i don't even know why the guys at Rtek retained the stock maps, they should have configured their chips with more conservative figures. the stock ECU was never intended to run that much boost and was why the fuel cut was integrated.
one of my old customers got the first 2.1 "standalone" from digital tuning and also learned the hard way that the timing figures are far too aggressive. he blew the motor tuning it to 15psi and brought the car to my shop, took me about 2 minutes to look through the palm to Rtek to tell him exactly why his motor turned to a brick. they shouldn't have ever experimented with selling those modified ECUs using their customers as guinea pigs with a false sense of security even with the disclaimers they put on their instructions. every other standalone has conservative base maps available.
