Hello fellow members,

I recently did a cam job on my 2008 350Z the people at Uprev did all the work they even installed some Injector dynamics 725cc injectors (which I thought it was overkill for N/A) they tuned it and threw some weird numbers on the dynojet (309.2whp-246.4wtq) weird torque numbers huh? Well the problem it that I turn it on every morning and turns on great, I let it warm up and then do what i gotta do and where ever I turn the car off and i try to turn it back on and the car struggles to start but starts up after about 5-7 seconds of cranking. i called uprev and asked them to change my injectors back to stock and retune it, but they keep telling me that the 725cc injectors were never the problem. They keep saying its the software. Can anyone please help me out here.

 

Your startup enrichment needs to be tweaked due to the unnecessarily large injectors.
