JLarson's build thread

My plan yesterday hadn't been for any gains. When I talked with RT in setting this up, the goal was just improving my safety net and laying the ground work for future mods. These gains were with a pretty conservative tune leaving more headroom than I had previously, but adding slightly more boost. I'll have to do an overlay and attach it here, but the most impressive thing about the new power curve is that although my peak numbers are only up 20 whp/10 wtq, the delta around 6.5k - 7.2k is more like 60whp, and it's definitely apparent.

Attached is my previous dyno run with spring pressure vs the current run with the solenoid.

1) Notice the delta around 6500 rpm.
2) Solenoid makes the boost ramp less abrupt.
3) Current tune is higher boost (about 2 additional psi) but safer tune (more headroom as far as injector duty cycle goes).

Edit: In case it's not obvious, I mapped this using Excel. The new dyno chart from RT is not overlayed with my previous run.
