Injector ??
If link works to dyno sheets, Great for feedback. Now my problem is during run i was told injectors where running 90% + @ WOT so tuner whatever was done cranked up fuel pressure stayed at 90 % be ok till u drop down in alt. , i'm @ 6500 ft now . So as I later was told this, I said can't live with that they installed 36# dropped down to 58 if I remember. OK now my ?? is can u install new injectors rescale them in parking lot and have all fine ? Car went in for emissions and bombed hydro carb test.

You'd need to (at a minimum) take it out on the fwy and log whats going on. Injectors aren't only about scale.

Well, you answered your own question. NO, it's not. Also, you didn't say 'how' he upped the fuel pressure (which may still be your problem 'cause you didn't put it back).

" Someone would have had to rescale the injector table or it would be rich as hell!!! " Don't think he remembered about pressure or I didn't tell me which my bad. Hate keep buggin him. Great Guy
So today I start trying learn ask shop "oh tune looks fine cam way to much overlap Huh standard 224/228 from Mamo lot of people on here have said your kidding do u know how big mine is? And it passed. Have u ever had to try and be diplomatic with an engine guy?

I think it is time to find a new tuner.
If you have been racing for 25 years, you should think about tuning your own car. It is just a frame of mind, instead of using a screwdriver and timing light you use a computer.

Hi: if you look at your uncorrected dyno sheet i.e the actual horsepower you will see the actual amount of horsepower your injectors are supplying at 90%. My guess is about 25% less than your corrected HP. Whatever that percent difference is, will indicate how much more fuel you will need to supply at a correction factor of one, which is aproximately what you will get at sea level (STP). Increasing the fuel pressure from 58 to 62 is small the difference in flow it is only about 2% as the pressure increase the flow increases as the the square root of the increase. I.e. an increase of 58 lbs to 116 lbs woul only net a 41% increase
