    2013 6.2 ls3 in a 70 nova Need an email tune.

    The car is a 70 nova. I have a fabrication/mechanic shop and put the engine in the car and did all wiring to retrofit. I have only tuned a few cars with hp tuners and they were 98-99 f bodys. This tune is over my head. The car has the dod removed and the vvt removed. It has texas speeds 235/239 .639"/623" 112 LSA camshaft. It has 3.23 Gears and a 3600 yank converter. It has full length headers and dual 3 inch exhaust with magnaflow straight through mufflers. it has a cold air style intake with the maf sensor about 5 inches from the filter end. I understand this wont be free, Im just looking for someone to help me get this thing out of my shop. With the attatched tune i removed most of the dtc's that I thought needed to go and messed with enough idle tables to get it to start and idle but if you crack the throttle it tries to lean pop and will only rev to about 1800 rpm. Thanks for the help. starts and idles but no rev.hpt

    Nevermind guys I found the problem. My customer took the intake tube off to paint it and put the maf in backwards so i had a huge mess of a tune in it just to get it to run. Now the car runs good. The wheels also came loose about a mile from my shop. Lesson learned check everyone elses work no matter what.
