Alright with all my bugs worked out, i finally got this thing running decently... took it to the track and its still slow, and still has rough spots in the tune..but i did get some datalogs so can you tell me how this looks..

Ms1, Main board v2.2, code v2.98 and an older version of megatune..

run 5 was done after a little pit tuning, after looking at the datalog on run4

One thing i noticed is the air temp shows real hot. I wonder if its heat soaking? Anyway, you got that idle set real good. Nice and smooth. Time to turn up the boost! Although you might need some bigger injectors. ;)

I will second, your MAT is really high for only 4 psi of boost.
I suspect you would get more power without the turbo and with some nice cool intake air. (You could do the math and calculate the air density. I'm too lazy.)

do you have an intercooler?

yeah, i have an intercooler..
sorry, the IAT sensor isn't exactly in the intake stream. I need to get a bung welded in to put the sensor in...so its kind of just chilling (not really) in the engine bay, hence the hot temps

Your just wasting your time without an actual IAT. And if this is the temperature the intake is getting... gag! You might as well put on a restrictor plate too.

It is used by the computer to calculate the air density and thus the required fuel.
