So I have a tune from a cammed 6.0, building a replica combo ( accept I "need" to use a LS1 style FAST 92mm intake vs a truck intake, yes I know but wanted to hear about fuel first) and I'm planning to use some DW 42# instead of FIC 540cc.
So assuming the only change I made was the injectors and the associated data changes in HPT how far off would the VE be? I know there are other factors so its never perfect but theoretically shouldn't it be very close?
And while I'm at it yes the intake is being swapped, the MAF/TB remains a stock GM 85mm/78mm on both so that should limit the change there but I know it's going to have an effect. The cam in each is a Summit stage 2 street .625/.625 226/238 113, both have 11:1 compression. Combined with the above injector change how far off are we talking?
Also, this is a fresh build. My assumption is it's gonna fire and idle no problem as the configs are pretty close, good assumption or should I make a few changes, I already planned to up the Idle RPM.
Thanks for any help.
