I知 supercharged as well
When I use to use e85 I had issues but some people that uses it don稚 . I知 running methanol tune now and only recently doing like 130mph went into limp mode rpms dropped and when I hit the gas it was struggling to go faster or over 40-50 . Codes came up with P0102 mass or volume airflow A circuit low . Come to think about it . This happen to me too as well on e85 engine shake and I had to pull over reset the codes and turn it on and drove home but same situation engine shake rpms dropp and wouldn稚 go over a certain rpm and that time cel was flashing . Now I got a rebuild from Cracking my pistons ring from using e85 mix tuned . Haven稚 had the problem happen again because Rafi cleared the p0102 code . But keep me posted on your findings

I've been driving the Lexus IS models for over 20 years...
I know nobody likes hearing this, but these ECUs / Engines are just NOT made to be Turbo'd, Supercharged or Tuned for that matter.. Period.
Something ALWAYS happens that ends either in catastrophe or dipping into the piggy bank way more after the product was installed..
I'm nobody's fool.

If you want reliability and speed: headers, exhaust, and weight loss are your friend. I知 seeing a growing number of people looking for OEM intakes to go back to stock.

I'm FBO with the intake and tune from RR for about 2 years now. Not a single issue.
I agree though. It seems like there is more issues coming to light with tunes and boost.
Ive been on the fence about getting a supercharger, the more I read the more I'm leaning towards not doing it.

The results are way too inconsistent, at best. My car hated the tune. It runs a 25 KCLV with the OEM tune and intake, so there is nothing wrong with the car. Runs like a champ now.

Have you guys monitored data before and after tune?
My car ran on the tune. It was my OCD in not seeing the numbers that I expected that led me to data monitoring that revealed the timing discrepancy. It seems common for people to throw tunes in their cars and never log or monitor data. I知 not saying that痴 the case with you. ISFpowered probably has daily data logs for 5 years, knowing him lol. If you think about the oem intake design, it痴 hard to imagine one can be better. The fact that you are supposed to dyno your aftermarket intake with the lid off is interesting. I wonder if the comparison dyno for the oem intake also had the lid off?

Today when I tried starting the car it cranked once and paused for a whole second as if the car died before cranking again and starting. This was the first time it ever did this. Does this sound like a fuel issue?
Also, If ignition coils go bad they usually throw a CEL right?
