I did a write up on here about my journey that you might be interested in.
But, the car made 808rwhp with that setup. Runs strong and since then I
had to get the transmission fluid changed (I’m running an A8) and a TCM unlock
so the shifting is right and it holds the rpm where I need it. Should have gotten
the TCM at the get go and it would have saved me some on tuning/retuning.
I’m tempted to turn the wick up to 900rwhp but I’m leaning more towards
less boost/less heat/less power = better road/autocross/open track car.
As to your previous question, regarding boost/e85/pump…
I’ve run a lot of high horsepower cars in California and the 91-octane stuff
is straight garbage. You’d have to run like 5 gallons of 100-octane to a tank
to catch up to the 93-octane in other states. Therefore, if you have a tuner
worth their salt, they are going to pull ALOT of timing out and the car will
run alright (it’s an LT4 with a 2650 after all) but it’s not going to have the
power and sheer hellcat-embarrassing power that most of the modded cars
here are showing. e85 is basically 100-octane and even with the worse gas mileage… still cheaper than running around with 91-octane. But, if I’m on a road
trip and there’s nothing else, I can take the 91-crap and run it with the flex tune.
