No need to shift early with aftermarket turbo. At that DA my car with stock turbo, high flow cat and Visconti e50 tune was slightly faster so there is a lot more to be had.
He'll still be at least a second slow. Even at lower speeds, such as 60-100 where the aero drag would be less of a factor, time is slow given the mineshaft air he was running in. Looks like some tuning refinement is in order.
With that DA your time could be much better. My best time was 8.27 with -410 DA. This was with a catted DP and Visconti e50 tune. With your DA I would have been in the 7's.
Graphite in oil has been around for decades. Arco actually used to sell Arco Graphite which was basically their normal conventional oil with graphite added to reduce friction. It wasn't on the market very long. I don't think their adding Krex to your oil is a reason to panic. I'd be surprised...
Visconti told me that they could do the unlock and retune my 2020 if I had the recall done. However, yours is just another reason you could not pay me to allow a dealer to touch my ecu.
I bought my car in March of 2020. They had five Supras on the lot. The Launch addition had a $20K markup, the three Premiums had $5K markup, and the lone base was MSRP. The base turned out to be perfect for me. Not only was it the color I wanted (red) but it also had virtually all the features...
Since my reservoir cap has never been removed I was a little reluctant to do so for fear of introducing moisture but I read that a two minute exposure to the atmosphere is insignificant.
I didn't know you could measure water content in the fluid. That is the best info I have seen as far as determining when to change fluid. I've tracked cars and boiled fluid before (91 300ZX TT at Willow Springs and Laguna Seca) so I know what it feels like. I've had my Supra for 3 1/2 years and...
