lately i've been doing some tuning on my turbo setup. earlier today at 2 separate times when i got on the throttle at WOT the 2nd to 3rd gear upshift seemed like it was slipping. this was with ~13.5psi and ~20* of timing. once i heard and saw this i let off and just coasted. i tried a few times afterwards on an open stretch and it shifted fine. the 1st one was approaching onto the freeway where theres a few bumps as well as i believe debris/leftover salt. the second time was in the backroads on a short open stretch and also possibly debris on the road. my question is(and those with turbo setups), if theres debris on the road when you get on the throttle, does this ever happen to you on the 2nd-3rd upshift?!

my shift pressures are above stock as well as the forced motor clutch amperage.
