takes a big gulp then revs...?
Just switched to bosch III's and installed adjustable FPR from south bay. Car idle pressure is 38a psi and jumps to almost 49 on throttle pump. No leaks. Engine is 91 305 tpi map setup. When I hit throttle, you can hear the engine take a big gulp and then vroooom. It didn't used to be delayed this bad. I know map systems have a little more "lag" but this seems a little excessive. timing is at 10 BTDC. Engine runs best at that setting when setting base timing. Tps sensor is at. 56v. IAC is new. Is this normal. Can't drive on roads yet up here, but it will break tires loose in barn. No backfires. Thanks guys

Honestly, though, you only give us 3 hours to respond to your unique situation? Really, many of us have barely gotten off work. Give us a chance to relax a little and check FB first. We don't do this for a living.
But, '91 TPI + MAF + mods = tune.
