modding a car that has been previously tuned
So I been buying some parts and just want to know if im safe.
My car was tuned on stock boost, with a full tbe and highflow cat, and a drop in k and n filter and it was tuned to max out with no knock.
What i did/will do:
I took out the highflow cat and replaced it with a testpipe and have not really noticed a difference in afr's (around 11.5-11.7)... Dont know about knock as i havent logged the car yet... is it something to be concerned about?
im about to put on a perrin intake and want to know if it will be safe... will it cause knock? supposedly it doesnt mess with afr's but it does raise the boost.
i later plan on getting a licp, uicp, boost controller(@22-23 psi) and a front mount. at that point i will be getting tuned though
