If I had the Dundon headers I'd go with the Dundon tune.

I used John from bgb.. With all the parts installed (stage I) ... His ecu tune really made the difference... Once removed all the parts and the bgb custom map the car was like switched off...

Thanks! Looking forward to it! My plan is to install the stage 1 tune for the next couple weeks until I can get the additional o2 bungs welded on the headers and installed. From there I will install the stage 2 tune and go from there!

Dynoed the stage 1 ots tune with my DMS headers and saw about a 5hp gain from not tune, not massive but definitely something. Stage 2 was about another 5hp....

Once you get a feel for the OTS tunes, give Jamie at Dundon a call. I got their 92 octane tune for my Dundon race headers, and it's really noticeable.. Low end torque from 3-5K kicks hard and pull to redline was insane. I logged some data for Jamie to review and tweak if necessary.. End result, no tweaks were necessary with my IDP and 82MM TB. Before you take the plunge and go with IPD and larger TB route, try upgrading the tune from Dundon.

Thanks all! My plan from here is to install the Cargraphic race headers and flash to stage 2. From there look for an ipd plenum and throttle body and get a custom tune through bgb as they are about 3 hours from me.
