Just wanted to send a quick thanks to Jason. Had been running stage 2 Cobb OTS for about a year, just recently purchased a Dizzy Stage 2 and it totally feels like a different car. Did install new plugs as recommended, and only have a drop in, CPE front mount, and a thermal exhaust for noise. Gonna have to keep the car another 5 years lol. Had a few questions about the tune, and Jason was nice enough to respond on a Sunday. That's not only a good performing tune, but excellent service and support too.

Dizzy Stage 2 on CA 91

- Start date
I have a Dizzy 93 and E30 tunes in my car. The tunes in itself are hard to describe, besides the car feels like it pulls harder and faster than the OTS tunes. The power and torque are handled very smoothly and don't roast your tires whenever you wanna step on it a bit. And the great customer service from Jason is also a great bonus! Would recommend picking up an aftermarket intercooler first if you don't already have one so you can get a "stage 2" tune and maximize the potential of your tune.

The responses above are just about spot on. Just as an observation- Going from stock to COBB OTS Stage 1 was great. Pretty noticeable difference felt. Went to COBB stage 2 after buying the CPE and car felt rough and almost felt slower. The numbers never looked harmful based on what the AP was saying compared to my research so I never changed anything. I also had my doubts about tunes through email since I come from cars requiring a standalone and the need for dyno-time. The Dizzy tune cleaned it up and raised the boost pressure by almost 6lbs at its peak. It's a great deal for those still keeping the stock turbo or still depending on the car for multi use. It has actually made me refocus on chassis/suspension/driving feel as I get my power fix from another platform.

Yes, don't know the hp gain since dyno is the only way to go on that and this car won't see one until I'm ready to go hybrid. I never intended on keeping this car this long so I didn't even bother to baseline 6 years ago. Baseline will have to be Dizzy stage 2 lol. Peak boost has increased dramatically though, at its peak, I would rarely ever get much more than 20lbs, we can now hit 25lbs peak boost. (I have not paid attention to the taper and whether or not its still as bad, but its not whats important to me at this time because of the stock turbo limitations) I have yet to send in a datalog, but thats what it is for now.
the power delivery can affect those numbers. For me, in reality the dizzy makes more power but because the stratified tune hits so hard so quickly it reads almost 50hp higher than the dizzy. Timed and instrumented testing shows the dizzy makes slightly more actual power though. Smooth onset - low Cobb guesstimate.
