So friends. 93 245+T
I have completed my 19T turbo upgrade, and the car is back together. I have my megasquirt waiting in the wings, but for now I'm still on the TLAO 2.4 chips.
If I run my HKS SSQV, the car will stall if I rev it while stationary. With the CBV installed, it doesn't do this BUT...
If I have a relatively quick transition from boost to braking... it'll almost always stalls (it fights hard though). I actually had Mike (TLAO) test the HKS setup on HIS car and it worked perfectly fine. So it is a sealed unit. For good measure I tried with upgraded o-rings and reported no change.
Mods.
93 245 +T. 19T. 3" AMM with 577cc/min injectors. Ebay IC. IPD turbo cam. Car was auto and is now T5. 3" exhaust with cat.
I have smoke tested and found nothing. I have sent propane around with no changes. I've sprayed starting fluid with no changes. I have boost leak tested (WITH soapy water) and found my oil dipstick tube o-ring needs to be sorted (this weekend). I have swapped AMM's around between known good ones. Same with IACV, TPS and O2's. My brake booster and my check valve "pass the tests" and there is no change in the stalling issue if I isolate them (with the HKS I can rev it while stationary and stall it).
I had the intake manifold off to clean the PCV system (which was remarkably clean tbh) so it has a new IM gasket and a new TB gasket with no changes.
Compression is GREAT and even across the board. Vac is generally around 22" at idle.
There's no change between the 15G and the 19T (for this problem) and this also entailed an entirely new downpipe.
Otherwise car drives great, boosts fine and is reporting fine mixtures.
I'm lost here guys... what COULD I be missing?
