My kit most definitely made 458 whp on a dynodynamics load based dyno at Forged Performance. They are one of the top VQ tuners here in the states. All on stock internals with meth at 15psi. It was definitely an aggressive setup for a stock block, but my car is not my daily driver. If you have some tuner that doesnt believe my #'s are possible, he can more than certainly pm Sharif@forged on my350z.com. I still hold the record for highest stock block vortech on his dyno. It took me almost a year to get the car to that level of power and reliability.
It appears that Dave has an uprev tune already on his stock ECU. If he is tryin to use that along with the UTEC, no wonder why nothing is tuning properly. The UPrev already messed with the fuel and timing. I just used the UTEC so anything in my tune was based on stock ECU values.
You'll need to get reflashed back to stock, or at minimum get reflashed for 600cc injectors for idle purposes only. If you did that, then you could put 'ECU' for everything in the 0% load column since the reflash would scale the injectors for you.
YOu can easily detune that setup by decreasing the overall timing. I had 17* timing at redline. The map I sent you I think had about 12* at redline, very conservative.
I guess we just need to know if you still have an UPrev tune on your stock ecu and then we can go from there. What do you have your base fuel pressure set at (it should be about 45 psi at idle with your vacuum line attached)
** ahh so it does seem you have uprev still on the stock ECU, so like I mentioned either get a full map retune of the UTEC, or dump the UTEC and get a full map retune of the UPrev. Cant use both.
I still would never use a reflash on a boosted G/Z but since you can't overboost a supercharger, its a little bit safer. But the inability to monitor knock above 5000 rpms with the stock ECU is my biggest turnoff and kill point.
