117hp back in 2013 we did 280 something dyno runs, changing from stock heads/manifolds to CNC heads and headers, and tested about 6(8?) different cam profiles (with each inj/head iteration) we worked on with our cam manufacturer.

if you have no rpm on the SCANTOOL (tach is irrelevant)...then it's CPS related (sensor, wiring, cam too far from sensor, etc) ..also note the 'only 500psi' for ICP is still borderline... the PCM should ramp up ICP pressure continuously during a crank no start to 1200+ so you may have more...

Nah, you’ll need it with 32’s

the rearmost part of the PCM needs to get cocked toward the centerline of the vehicle.

meh. I don't have any use for a 80% or 100% nozzle tbh...but people will buy what they want stock nozzle up to 375rwhp 30% up to 450rwhp 200% up to 700rwhp, but can still be tuned as clean as a stock nozzle. 400%'s aren't clean enough to use on the street. We make 500-550rwhp on a stock HPOP...

not always fuel volume per time HPOil volume per time consider and compare each metering orifice

very close. within 5CFM

on our cylinder head flow bench, a 6.4L head flows about 60% more CFM than a 7.3L head...stock to stock HEUI is definitely an issue wrt to performance...but unless you want to run a solid/no coolant (7.3L) head, going to common rail isn't a gain. if you want to run coolant in your 7.3L heads...

cab bushings

yeah, if we charge x for CNC porting....then it would not include surfacing/new valves/seats or any other machining services. stock diam valves are within .020" of cylinder wall, so you'd have to notch the block for a larger valve..but then you're just tucking the larger valve into a severely...

we often do CNC porting (keeping stock cam) for guys at high altitude that aren't necessarily looking for 700hp, and it absolutely improves the cleanliness of normal-ish driving. but 90% of the time, excessive smoke is from tuning or mismatched parts for the application. < ie, 37" tires 3.xx...

in short... stock cam/heads are routinely good to 650rwhp stock cam w/ our CNC head work is good to low 700rwhp anything over that will need CNC and a cam. don't plan on running coolant in your heads if you're looking for more than 1000hp

sounds like this could be easily fixed with some tweaks to the ICP table. shoot an email to [email protected] and we'll shoot out another chip/programs.

the pop and white smoke is almost certainly going to be a nozzle issue...hanging open dribbling fuel into the cylinder.

range selector feels like it's clicking into each detent? fluid level OK? any recent service that may be relevant?
