I got my car tuned yesterday by Hal at IP. I have an 04 350 with some bolt ons. I have Stillen headers, Kinetix HFCs, Stillen dual exhaust, Motordyne 5/16s plenum spacer, RPS flywheel and clutch. I got an ECU flash tune. I had a technosquare reflash on there before and wanted to see how much more I could get out of a tune. Hal was about to get 9hp more over the technosquare flash. It wasn't about peak numbers though, he was able to smooth out a lot, especially the A/F. The first pic is after the tune. The second pic is the before and after with A/F. The red is before and blue is after. Look at the A/F difference. The third pic is before and after again with torque. The red is before and blue is after.

 

Very solid gains.

 

Very nice gains. Hal is a great guy, I seem to run into him fairly often at various race events.
