Example being: If the car is seeing KR (Knock), you can’t just dump fuel up top like some “prestige tuners” have been known to do and then expect the tune to be safe because 9 times out of 10 these “safe” tunes are going to pop motors and cause owners to point fingers at the tuner for blowing up on their almighty “safe” tune. dump fuel to remove KR? are you kidding me? thats like putting a band aid over a stab wound. If you are getting KR, you remove timing. The reason why you are getting KR in that cell (or cells) is because of timing to begin with. When you remove timing, it richens that cell. When you add timing it leans that cell. I am not sure how difficult tuning your cavalier can get, but there is ALOT more to that in the LSx world then adding fuel to take care of KR… there are obviously many different levels of tunes as well…obviously a bolt on car is just going to have a wideband thrown on it, tweak the AFR and add a few degree’s more timing and remove torque management and what not… but when you get into H/C/ aftermarket intake cars, you are basically re-doing every single parameter you possibly can… were talking High/low octane spark, PE enrichment, MAF recalibration, Primary VE, Base running airflow, start up running air flow, OL and CL etc. I could go on all day. --- _[View the full topic](https://forums.speedlife.net/t/new-local-domestic-tuner/253159)._
