I just buttoned up my car after a four month turbo build in my garage. Heres a run down of the setup
Stock shortblock with 317 heads and ls6 cam
TC76 with a front mount
This was my first turbo build and i purchased hptuners for the sole purpose of learning how to tune this setup, i have done very basic PE and system changed on bolt on and cammed cars but nothing serious at all.
i followed a couple tutorials and online guides and books and got a general run down of the tuning setup and im just going to take it very slow and learn as i go.
Fast foward to tonight. finished up the car mechanically and pulled the tune off of it to modify. Old setup was a heads and cam setup that did a little over 400 rwhp. Modified spark and VE, changed gear ratio and tire size for current setup, changed injector values, lowered the idle to 850 (was at 950 for cam), basically followed the 2bar SD setup on the help section.
Good news: AFTER FOUR MONTHS SHE FIRED RIGHT UP!!!
im ridiculously excited about this
Bad news: Something is up with what i can only imagine is the base tune.
It will idle fine, wideband at +/- 15.1 at idle, sound great, for about 10-15 seconds. after that the rpms drop and the wideband reads lean at approx 18 and it chugs really badly. if you attempt to touch the gas it bogs really bad and basically kills it.
Can someone take a look at the base tune and point me in the right direction. i have also attached the very short log of the start up
