Preliminary tuning with just the wastegate spring yielded 454whp/290tq at only 13psi and 8300rpm’s.  With the addition of the AEM integrated boost controller, we were able to pick up close to 60whp mid range power with the identical peak boost pressure.

After we were able to create a nice linear boost plot, we then increased the boost pressure to roughly 17psi for the AEM high boost setting.  This  set-up was built to handle 500whp on 93 octane (pump gas) and we easily achieved this.  At 17psi this set-up is making 502whp/362tq.  Unfortunately we had a bit of tach pick-up interference which is why the torque values are erratic on the below dyno chart.

We have a few minor changes to make with the set-up prior to the e85 dyno tune.  On e85 we are expecting to see power values in excess of 650whp.  Stay tuned for more information to come!

This set-up features the Cobb Front Mount Intercooler Kit, Cobb Blow Off Valve, Cobb Turbo Inlet Hose, Injen Cold Air Intake, Cobb 3″ Downpipe (True 3″ down pipe modified by AV), HKS 3″ exhaust, and Cobb AccessPort. We managed to pick up 60whp midrange, 40whp peak, and over 130whp after 5500rpms with tuning the Cobb AccessPort!  Unfortunately, we were limited to 15-16psi of boost pressure due to the crank driven fuel pump (CDFP) pressures dropping below 1200psi. With the addition of a CP-E CDFP we expect to see this set-up to easily hit 300whp around 20psi of boost.
