Numbers? I had my baselines done before I got the Renntech ECU tune, Renntech exhaust, and I put the K&N filters on. Going to go back soon and get the afters.

I will be very interested to see your after tune numbers. What was your baseline?
I'm at 442awhp and 517awtq. I did 4 runs and they were all consecutive.

Three runs back to back on a DynoDynamics Dynotech, peak 375AWHP, 460AWTQ baseline witha very flat torque curve, from 2500rpm, dropping off approaching redline.

According to the shop, who is friends with the shop across town that has a Dynojet, the HP numbers are usually 12-15% lower on the Dynotech, but torque is pretty comparable. The way the different dynos work is all about how they capture torque and do the math for the HP as I understand it.

What's interesting, is the stock dyno numbers that Renntech shares, show 340 hp, 450 tq on the peaks, but their torque curve isn't flat on the stock numbers at all - although you could land a plane on the after numbers. The butt dyno confirms that the toque is on...like from 1000 RPMS - full torque. You blip that thing at idle and it plants you.

Renntech should be giving me the new update that unlocks more torque, but I have to figure out if I'm allowed to yank the ECU and send it to them, or if I have to let the stealership do it to keep all the warranty in tact....

Was thinking about getting new dynos now, and then sending it back to do a 3 way comparison.

Subscribed to see what happens. Marcins car went 12.417 with a 2.0 60ft with those #s I wonder what the renntech car is capable in the 1/4. Since the dynos can be off on numbers the best way to know is to see how the car moves out.

If I read this correctly using renntech tunes may keep warranty?
