Hey so I have an issue that occurred only after changing out my skunk2 pro manifold and 70mm throttle body to an ultra street and 74mm. when i try to accelerate at partial throttle the cars rps drop for a second or 2 then come back on and over and over, revving a bit higher each time. when i floor the petal however it revs right up to my 4700 launch control limit and bounces of of it as normal. any advice will be helpful thanks

I had a similar experience not sure if its the same problem but mine would bog and would not go past 2500 rpm when driving but would 2step fine it ended up being the tps it wasn't calibrated correctly not sure if u calibrated it when putting new throttle body ony

yes i calibrated it but i will try again thank you

Your TPS is not working in the datalog.

ok i thought it was working because i calibrated it and it changed to -5 and 60 now im noticing it reads those values no matter if my foot is on the pledal or not any ideas of what may cause this

Usually the TPS, sometimes the wiring, sometimes the MAP & TPS swapped.
