a small shop in orlando tuned it, guy named brian lee. tuning time maybe lasted for 7 pulls down the street and 15-20 mins of driving. it was 75$. i don't know what rod knock is? it doesn't do it at idle or above 3000 just low in the rpm with a big dump of the throttle. rod knock sounds like a very bad thing. ALSO, John Vega- after i put the turbo kit on, i'm coming straight to you. you did a friend of mine's car and it has run flawlessly since the day you tuned it.
