per hour injectors currently on the '93 900T Commemorative -- an LH 2.4 Anything above half throttle and it really stumbles -- fuel cut of it feels like. Yes, the 300ohm resister has been spliced into the AMM. Really becoming annoying. There is a LOT of power I can tell if I can just get beyond this issue.

BTW, this is the car that was previously owned by Bob Jones in Northern Viginia, for those of you who remember. It also had a Talliaferro Stage II ECU with the rev limiter removed. Rev limit now controlled by MSD 6-AL ignition.

The RRFPR and 30 # injector set-up worked fantastic on my '88 SPG, but that was 2.2, so now I'm going back to a 3 bar. Hopefully the 2.4 can handle a more linear fuel progression rate of the 3 bar. I would think so.

Keep the 300 ohm resistor? Or remove it? The 30# / hr. injectors are staying in there.

Ive pretty much perused previous threads:
http://www.saabnet.com/tsn/bb/performance/index.html?bID=70591

The trend there seemed to be going with 3 bar as well, but what I couldn't surmise from you guys was whether you were running LH2.2 or 2.4. I'm getting the impression there, as well as taking to Jak, that the 2.4's more complex fuel mapping is kind of doing automatically what the RRFPR is fooling the 2.2 into and when combined, is actually flooding the cylinders.

Guessing at this point, but the logic points in that direction.

The 3 bar goes on tonight and I'll take it out for a quick test run. Tomorrow I was planning on getting it dyno'd for Jon Williams header. I'm hoping I'm not jumping the gun getting it tested tomorrow. OTOH, the shop I'm taking it to is a EFI guru, specializing in Electromotive, Bosch and forced induction tuning, so if anyone can settle things down, this is the guy, hopefully.

Comments welcome.
