Hello, i am excited to have joined the HP Tuners family this week and i decided to get myself an MVPI2 after spending money on 2 different tuners who were unable to leave me satisfied with the tune for my truck after doing the following mods. 08 escalade EXT 6.2/6L80E with 223/234 .625/.625 112 lsa cam, speed engineering longtube headers, borla dual exhaust, magnaflow hiflow cats, Ported L92 intake, LS3 TB and 2800-3200 stall, tru-cool 40k AT cooler. The last tuner locked the ECU/PCM and vanished. Truck is having the following issues: Cold starts sometimes dies/stalls when rpm is constantly fluctuate between 600-1000. Same thing occurs when driving, it stalls at times at the lights when i see rpm drops to 500 get the stability track and traction control lights/warning come on and die but i can easily restart truck again and continue, is shifting horribly, i have to give it gas and increase rpm to shift to 1st, 2nd and 3rd and once i get going it kind of downshifts, manual shifting is much easier and less revving, i know the stall makes a difference from stock but am not happy at all and keep getting screwed by letting other tuner basically tell me how bad the other guy did and i end up with the same product anyways. Please help me, i finally was able to learn how to data log and get a copy of the current tune. Please let me know if i did alright on my first mission. For the log, i was only able to log what is a normal day driving for me with stop and go traffic and a little freeway time. My apologies before hand!!!
