Finally got to the dyno on Saturday. Same dyno I used before, a Dnyo Jet. Previous numbers were--HP, 471.8 and TQ, 498.1 After the Sean Roe SCT program, HP,500.4 and TQ, 507.2 Was it worth it to me?? I think so. We did an A/F reading and it's a little lean still at 3700 RPM and at 5700RPM. I'll fax the A/F chart to Sean and send the SCT back for a slight change. Don't think I'll get much more from it, but worth a try. 2006 Coupe, no cats, three inch exhaust, Belanger headers, K&N air filters and intake, and the Sean Roe single plate trottle body.
