Sounds just like my car. I have BLM's of 116-118 left and 134-138 right. That and before it even heats up and goes into closed loop the right BLM is in the 130's, while the left is still at 128 where it should be in that cell.

Other than that the car runs great with the tune I got from Ion Soltan(Madwolf). The car is really driveable, even with stock 3.42 gears. I have zero surge except if I let the revs fall too low taking off from a dead stop in first gear. I don't feel the car pulling harder though. It just keeps pulling past 6k instead of falling off like the stock cam. I won't reccomend it over anything else since this is all I have expereice with, but I'm happy with it so far.

 

I recently had this problem after I installed new injectors. I was trying to get the Inj Const set correctly, and I noticed the PCM was using cell 18 during normal driving. I first noticed that it would go into 18 whenever revving it without load. After doing a lot of reading, I'm pretty sure now that what happens is the PCM will use cell 18 rather than going into a cell with really really low BLMs. It did stop using cell 18 as much once I got the BLMs straightened out.

 

Does cell 18 cause it to lose hp or what exactly is it?

 

Well. did you find the problem? Mine used to die even without the A/C on. Just by coming off cruising speed onto a stop light.
The revs go way low and never recoup. I fixed that problem by doing the throttle body mod. Now I have a nasty suction sound much like a vacuum leak would make, but at least I am not stalling her at stop lights anymore. Only if my A/C is on.

I have PCMforless and we have been around this tree a few times already. Bryan has me up in the low 30's for advance and he upped my IAC some. I also added an MSD blaster coil. All that has helped, but has not cured the problem.

Car runs awesome though.

 

Actually I havent even looked at it anymore because I have a clutch thats going bad now. The guy thats putting in my clutch is gonna check everything else and fix it all at the same time. I tell you when it rains it pours my way.
