I recently had a few issues with my 87 and 93 octane tune from brenspeed. They checked the tunes and said it had to be something mechanical and suggested I clean my TB as it would be more sensitive to buildup with 93 octane fuel.
I could see this being true if the 87 octane tune worked properly, but the 87 tune is a DOG.
Example:
When going around a corner I clutch and downshift to second and then correct the rpm and let the clutch out and begin to accelerate. On the 87 tune, when I begin to accelerate I'm usually at 1500 rpm or so. As I depress the gas the car feels like the clutch is slipping as it accelerates to about 3k rpm. If I shift to third before that, its the same feeling until about 3k rpm.
However, shifting from 1st through all the gears results in normal acceleration.
The 93 octane tune wont even run, the car kills itself as soon as I let off the gas.
I could SEE it being some sort of buildup on the TB IF the 91 octane tune didn't work FLAWLESSLY. No issues on this tune whatsoever.
Is it just random that this tune chooses to work fine, or do you really think that cleaning my TB will clear up the problem on both the higher octane and lower octane tunes?
The only reason I ask is because with less than 4k miles on the car and I cleaned the TB when I put the CAI on less than 2k miles ago....
