You need to get your car on a Dynojet and play mix and match with all your injectors, fpr's and chips to see which combo works best. Until then use 3 bar fpr, blue top injectors if you have larger turbo... If no larger turbo, 3bar fpr and stock white injectors. You didn't say if you have any mods on your car!?! Set up dynojet day and bring all things with you to test that day. I had similar issues with JAK's chip. I had mechanic test and replace everything possibly related to the system, spent lot o money. But when I have all stock components in, fpr, injectors, stock fuel chip, the car is fine! So it was determined that the JAK stoll chip was not compensating for the T5 red top injectors. BTW, SD 30's red top ARE the same as the T5 red top from an Aero 9000. 30# with 2.5 bar, and 34# with 3.o bar fpr!!! My car acted the same way as you are describing, strange reving from 1-3K rpm, if it did settle down, I could drive, but sometimes stalled at streetlights or when decelerating to a stop. Dangerous. I also had same fuel cut-out issues around 4-5K rpms. On what I said B4, if you're gonna run more fuel, you better have a chip designed to provide proper air/fuel ratios ACROSS the board- at idle, low rpms, midrange, highboost, flat out accelleration etc. Otherwise you get a poor running car. I personally get away with 3bar fpr, and the blue top injectors = 27# per hour along with the stock fuel chip. It is alittle rich on bottom through 3K rpm, but not nearly the catastrophy of running the T5 red top injectors (even with 2.5 bar fpr). T5 red top with 2.5bar fpr= 30# per hour, T5 red top with 3.0bar fpr=34# per hour. If Gary from SD is willing to send me a tester/demo fuel chip, I'll put my car on Dynojet again and get baseline to see HP, torque and air/fuel ratios! Then I can recommend it or not! Let me know Gary.
