Sooooo,

After reading some more about TBI tuning my 7060 $85 PCM 454 93' K3500, I realized I haven't probably set it up exactly how I should. It runs good but still needs tweaking. So I'm starting over.

Can you check my BPC math please?
From davew's calculator I checked the BPC for the stock truck.......his calculator says 134. MY OEM BANC.bin has 142. thoughts? This is for 80lb injectors.

Only mods the truck has is a set of JBA headers and a 3" exhaust with a fuel pressure increase to 16lbs.

Using this formula: NewFlow = OldFlow * (SqRt(NewPsi / OldPsi))
I get 92lb injectors.

Plug that into davew's calculator spreadsheet and I get 119 BPC value.

So would you suggest one of the very first things I change in the .bin is put the BPC at this 119 value?

Thanks,
Ryan
