K well here's the story have a buddy with a Lmm with a dsp 5 as we all know we can't read the ****ing ecms after this is done so I didn't have the original tune another buddy did but it got lost erased whatever so I found a tune that matched his os but the difference is his had a voltaged based maf the os I had has a frequency based maf so I just switched that then we flashed it in no power? Then when his tuck threw a maf code it had power back except for 1st gear wtf? I took the dsp 5 off threw a single tune in threw maf codes an no power I tried a dozen times to get something to work over 5 hours finally gave up for the night his vin number is 1GCHK23698F193766 I found 12628594 as what his os should be anyone want to check thus out for me? Going to have him take the truck to a dealer see if they can flash him in a stock tune again so I know I have a stock tune that's correct to build off. Any input would he nice thanks ahead of time

So to bring this back up took truck to GM flashed it to stock re did dsp 5 got it running then he lost the Turbo so put a cheetah on it.....well now it throws underboost codes just driving normal so I rescaled the boost didn't help turned the error time to 655 still doesn't help then it throws map code 107switched in a know good sensor still get code moved the error time up on it to 655 no help there still throws both codes turned them off now it trys setting codes but just studders and bout kills the truck wtf is his ecm shot or what?

If we rod the living hell outta it no problems normal driving is ****in retared wtf is going on here I've swapped sensors messed with everything I can think of either I'm missing something totally stupidly obvious or there something else in the ecm screwing up I'm losing my mind over this :confused:
