hey all

I'm new to hp not to tuning.
Question as to throttle management... how do i get it to open properly?
I'm getting ridiculous tps position vs commanded.
Please help me get started.

86-88% throttle is actually fully open; these cars don't hit 100% on the TPS. You are only making 1/2 of stock boost levels, so there may be a boost leak, or a break/leak in one of the boost control vacuum lines. Fuel trims are also high at cruise which could be due to an air leak. IATs & rail pressure look normal. So I'd inspect your boost control vac lines, do a boost leak test and check/tighten your charge pipe clamps.
