FPBig28 22psi Log

[DSMPowerTSi]

All I logged was RPM and Timing since I accidentaly picked TPS instead of o2. This was 22psi pump gas, any lower boost on the fuel setting and it would stutter, WOT knob on Translator maxed out. Mods are T28, 650's, FMIC, Exhaust, GM Mas, Intake, etc....


RPM Timing
4504 19
5368 21
6336 18
7216 19 < Shift to 3rd
5096 38
5532 18
5980 16
6376 18
7004 19
7228 19 < End Run

Basically should I turned down the boost or click it into RPM mode and richen up 5500-6500?

BTW, The jump from 17psi to 22psi was night and day.

Definitly looks like you are knocking around 5500

PS tweak your logger so you get a better sample rate

Try logging TPS,RPM,timing, and O2's only. Find a find a good open road, get it in 3rd gear @ 2500 rpms, start logging, and floor it (WOT). Don't shift, just take it to readline, then ease off. You need to log as much of the rpm band and no shifts.
I'm running 17lbs on my t-28. I would love to try 21lbs., but I'm a chicken sh!t.
Post a new log if you can.

I'm going to do a new log tonight after I fix my byte timing on my logger. I know that the T28 ran its best time on race gas at 21lbs but I cant lean out my WOT knob anymore. If I adjust my base leaner its going to throw off my idle/cruise tune. I figured if im picking up 19 degrees by redline with just that one dip in timing, after that is straightened out I might as well leave the boost alone, because it feels really strong. Thanks for the replys

i was running 20 psi running a little rich but its rare i get on my car but the other night i mad a 3rd gear run and the car ran 22 psi for some reason but the a/f was fine but i haven't got to check the timing but the car pulled HARD and smooth 22 psi fells so much stronger than 20 its almost unbelieveable, i love the big28 its got to be the funnest turbo, but i also was wondering how safe that much boost is on 93 octane on a high mileage car
