Default Installed 30 lb accel injectors, hot start problems

I scaled my injector sizes to 36lb at our fuel psi but after looking at this thread it is saying to use 34.64

https://ls1tech.com/forums/pcm-diagn...injectors.html

The car runs great but I am having some hot start problems. It has to turnover a lot before actually cranking. Only happens on hot starts not cold. I have HP tuners and my car is a 01 M6 vette with HP TUNERS. I installed the injectors so I could spray 125 shot ( was seeing 134% duty cycle before)

Only mods are k&n and 125 shot.

Any suggestions to fix the hot start issues?

From what I can see they are 29.4lbs/hr @ 3 bar.

You need to use the excel sheet for injector flow rates and then cahnge the IFR values.

I scaled the IFR and the curve remained the same but shifted upward. My first value was 36.00 and the others upshifted accordingly. That's where I think my problem is . My base number according to the formula should be 35.4 i thought but that other thread is saying 34.XX

Are there any hot start tables I need to change that would be causing my startup issues? It runs fine otherwise.
