This week had to clean up a 2002 C5 A4 with 8 PSI supercharger.

This is the third time we have had a customer come to us to clean up a mess and ended up with a blown engine from this so called tuner.

Customer had gone to this tuner for a "dyno tune" this JF blew the engine up while on the dyno !

JF then talks the guy instead of fixing the damage he did to buy from him another engine.
This high added cost plus a cheapo water/meth kit from the ECS vendor.

Car is tuned again and runs like crap and so is the A4 trannie

Customer comes to us for a total retune. He of course is 3,000 miles away in Flordia and has bought a tuner tool so we did this all via emails requiring them to do a testdrive with a scanner and email us the recording to analyze which we did and is the results on the left side of image below.

We suspect a problem and start asking customer questions to lead to part of the why car was a shitbox.
The water/methanol nozzle was installed BEFORE the MAF !

Which of course would flood the exposed sensor of MAF and cause incorrect airmass and line pressure.

Customer emails us the PCM flash file to analyze to find the normal sloppy and ill experience in this JF tune.

Misfire tables were turned off, so was torque management, timing setting were junk, and worse is they talked customer into 60 lb/hr injectors plus how much richer it gets when the w/meth is on

At best this setup needs a 42-48 lb injector.
MAF tables were mucked with and DTC error codes were turned off that did not need to be.

Closely look and the Before and After results, everything from WOT timing, to what the final horsepower and Torque values are to see for yourself that this JF - FastProms should NOT be tuning his own car much less the big bucks you have spent on your car.
