I just installed my powerlogger and logged a run at 13 lbs of boost. I noticed I'm running lean at WOT. I believe my MAF number should be 255 at WOT? I have not tried adding fuel to chip yet. I wanted to make sure my MAF and translator are good. fuel is rising 1lb with 1lb of boost. FP is set to 43lbs vacuum line off. My current set up is stock engine, transmission. TA-49, 60lb injectors. deatschwerks fuel pump, 3" dp with cutout. Pypes exhaust and 85mm MAF with translator. PL fiile is attached. Any advice welcomed. Thanks in advance!

Aem gauge. Not going to be able to open up the translator until tomorrow. I will post them tomorrow morning.
 
I'll log another WOT log and post my translator settings tomorrow. I appreciate the input from everyone!
 
If you get the throttle completely open, and the airflow still doesn't come up higher, then increase the WOT knob in the translator. At 13psi, I don't expect you to hit 255gr/sec, but maybe 210-230gr/sec.
 
I double checked my TPS today prior to another run WOT. My TPS looks perfect with the key on engine off. My TPS still remains well below at WOT than what it should. This may also explain why I have had trouble building boost past 13lbs? I have Razors Alky. I read that I could tap into his TPS harness.This is where I made my connection for the powerlogger. I assume this is okay? Could it just be a faulty TPS sensor? Open to all advice

Disregard TPS. Adjusted floor mat and numbers look great. Blow to the ego but at least a cheap fix financially! Thanks!
