those downpipes look sweet, never seen or heard of the Savu brand, was it the same cost as Keller? Are they 3.5"

Seems fine. E20. Haven’t record anything on draggy, but logs are good. Timing so so as usual.

I'm happy with this run. I backed off the ethanol content from E40 down to E35 on this run. With the colder air the ECU is asking for a lot of fuel and trims we're maxed. It's in a much safer range now with my setup. This is the fastest I've been in positive DA. Just ordered Project Gamma secondary cat delete which should help me pick up a bit down low.

Check your email for raw file. Going to hold off on tune, I want to see how my car responds to the lower downpipe. I want to go in steps so I know what to attribute gain or loss to. That being said I'm talking to Utku Noa about a custom ECU/TCU tune.

Air was so good on that run. 50% humidity makes a big dif. What DA have you been running in lately?

Just ordered Project Gamma lower downpipes. Lets see if it frees up some HP.

I am curious. You have lots of documentation so your results should show the gains.

Thx. I should have them on hopefully by next week. I'll do some Dragy runs and corresponding data logs.

I had a dealer appt for the car the other day, so had to remove the JB4. I’ve been running e25 with a splash of boostane and no tuner, just downpipes and intake, the car is actually pretty impressive with no tune. The dps and good fuel seem to sure help vs stock, it feels like it’s running strong.

If anyone is concerned about tuning, I’d suggest downpipes and intake, w/ good fuel, there is a noticeable bump in power without the warranty concerns.

I’ve put a deposit down on a 911 turbo s so I’m not sure I will even tune this car now as I don’t think I will be keeping it long enough.
