My recommendation? E85? New injectors, more boost, etc discuss with Jonx96, he just remote dyno tuned my car yesterday and took care of a long standing STKR on throttle openning issue that a few tuners could not solve which was induced into my tune some time back by the tuner you are contemplating using. These big guys just want to take your money, shove a canned tune into your car, not listen to what your trying to explain to them as maybe being the issue because “their pros and know better” premadonna BS don’t have time to listen to you, that’s not custom in my book. My issue was induced into my so called “custom” canned tune I was given which was for an automatic which I tried to get the point across I’m a M6 and was repeatedly told “that don’t matter” and guess what? it does!!
@jonx96 can do what your looking for at a cheaper, more attentively, and more so more respectfully experience. Proof is in the pudding, see bellow, see any STKR anymore? Look at those fuel trims, BANG on!! And he didn’t fix it by jacking my knock sensor settings up to the moon, turn off critical sensing like miss fire detection (which is what hurt my engine, THANKS pro tuners)
