They all come from the same Chinese factory overseas. There are a few vendors that have them available on their site (EastCoastSupra) or off menu (P2uned can order them and they have installed a few as well).
Botti is not the only one that does that. I've had that with John Visconti as well. Both seem like "if you aren't spending loads of money or getting them fame, you can wait" kind of mindset.
The car on stock maps can run up to e25 from the factory so if you can get to about 6 gallons, you can add about 5 gallons of 91/e10 into it to bring it to e25.
I would consider flashing back to stock first and seeing if the valvetronic issue is still present. If the issue is still present, you may need to look into it further from a mechanic's perspective. If not, then it's a bad map and will either need to be corrected by Botti or if you would go with...
I did all the SPL parts:

I went with the AfE bars (front and rear) and in conjunction with the HKS touring springs and SPL parts (oh that was very expensive), made the car handle like it was on rails.
That depends on your tuner. Factory cars will generally have the same configurations for the model year so the tuning parameters are within a certain range of each other. A tuner will ask you to data log to fine tune their baseline maps to get you the most out of your specific car and area you...
For remote tuning, you would need the Ecutek dongle (Bluetooth; data logging from your phone) and USB lock key (used for PC; flashing maps to the car, used in conjunction with the dongle via USB).
Ecutek doesn't have "canned tunes" as tunes are provided by a Ecutek tuner. Each tuner will have...
There are two options for strictly flex fuel. One from Twisted Tuning and one from Visconti Tuning. Both uses the Zeitronix CANbus ethanol adapter. The Twisted tuning requires wire taps into the DME harness and the Visconti Tuning requires repining a wire harness from the inside of the car...
I would buy ECUTEK with the tuner you plan on going with as they will generally give you a one stop price.
Downpipes(catless) anyway are whatever works for you price wise and more or less ignore the brand name itself.
Catted downpipes are more expensive and as long as it has an HJS cat element...
Catless downpipes are more or less the same. Diameter and build quality are the big things to look at. Most of the cheaper ones are from China (which is fine).
You WILL get a CEL with a catless downpipe. The simulators don't work from experience with folks that have tried it. The only way is a...
