My car was on the dyno yesterday.
1st run 197.17 hp 182.11 torque
2nd run 198.82 hp 180.50 torque
I have a DA sports kit, it was set at 6.9 psi but my split second piggy back does not seem to work it was not adding any fuel whatsoever in boost, which made me pretty much waste my money other than getting numbers on the dyno. My friend whom was doing the tuning became afraid to even drive the car anymore after he saw the 14 to 1 air fuel ratio all throughout boost which he could do nothing about it seems like the split second just does not work. And the funny thing is I am getting a running rich code on the CEL, yet the car is running dangerously lean. He said if this fuel issue can be resolved I should be able to gain an easy 20-30 more whp at 7 psi but I'm not sure what exactly to do. I set the car back to 5 psi for now and dont plan on driving it until I resolve the problem. If anyone has any suggestions I'd be more than glad to hear I'm running 440 cc injectors as my only fuel upgrade. I dont know if I should get a fuel pump, and fpr or just entirely get rid of the split second and go with a greddy emanage and keep everything stock in the fuel system except for the injectors. I'm having trouble inserting the dyno picture if anyone wants to see it I can email it.

You usually get the rich code when you are cruising or softly driving. Also make sure that the AFR is not too far away from the turbo, and it is working properly.

I have no cat so they plugged the wideband into where the 2nd o2 sensor goes after the cat, I normally have my stock o2 sensor plugged in there doing absolutely nothing. They were able to make changes with the split second out of boost at some lean spots which I had(especially a hesitation which I had when first giving gas from a dead stop and I believe there was a spike to 18 to 1 somewhere in the map as well) but once in full boost it would not add more fuel I believe he brought the numbers from the 8 ish range in one spot all the way upto 12 to try and see a change but the a/f ratio was still 14 to 1 straight across each time shutting off the car to make changes as split second requires.

where do you have the vacuum hose coming from the split sec connected to? seem it only sees vacuum not boost

those are still good numbers for a GT, expecially the tq... hopefully you get your car running at healthy AFR's though. Best of luck and good numbers!

Nice.

Those numbers are just about what my IS300 dyno at. Cept the IS is a pig compared to the Celi.
