vette tuning. tb issue? 03 z. monster. stg 3 light weight flywhel. fast 90, ls2 tb, dynatech longtube with 2.5 x pipe. problem occured after frost tuned it and also changed the tune back to reading the maf instead of speed density from when my friend tuned it. took the car to the track a few weeks ago. when shifting into the next gear and getting back on the gas. the car feels like it is hesitating or is a delay in how fast the tb response. happens in every gear for me and 2 of 3 shifts for another friend. last week i got a code 1515 also(havent found any answers on how to fix it besides that it might be a lose connection but everything looks perfect). i then took the car out and logged it and did some no lift shifting. between shift while doing zero lifting, the tb was recording 100% down to 20% when changing gears, then back to 100%. (i never lifted.)
is the tb closing because it is automaticly doing it or is it because im shifting at redline and hitting the limiter? if it is the tb automaticly closing on its own, how do i turn it off?
thanks for any help givin because im
for the last 2 weeks trying to find answers why its having this problem between shifts and its killing my times at the track

Maybe Im not up to par but the only limits I can find on the ETC is in Torque Management, ETC TPS Max. Leave the top row at 0, High light everything from 10-100% and across to 8000rpm, change to 100%.

Thanks alot for the help. It ended up being the etc table was 300 rpm lower then what the rev limiter was set to. This makes such a difference in the car and how happy I am with the car words can't describe it
ect and the rev limiter were the same, raised the revlimiter a tad and raised the ect a couple hundred more then the revlimiter
vettes and fbodys have ALOT of diff tables. glad its fixed for sure.
now to mess with dfco to let it shoot some flames = p
