i know i know.. but ive been searching around and i could not find an answer that specifically answers my question. i have an 03 enthusiast and i was wondering if running an intake, test pipe, cbe, 5/16" spacer, and mrev2 will cause me to run too lean to drive WOT. if so, is it safe to drive WOT with those mods minus the mrev2 (i/tp/e/spacer)? thanks

 

Every car is different. Your car with all those mods may be nice at 13:1, others may be nasty lean into high 14's WOT like mine was NA before the tune.

I can tell you I drove my car NA, untuned for probobly 5-10K miles, AND I ragged the $hit out of it, EGT's got so high on 5th gear pulls the fiberglass packing in my mufflers would shoot out in little fireballs (young, and dumb) and it seemed to not have impacted that motor.

I later tuned it, it made good power (for the time) and it ran like a raped ape till I later blew it up turbocharged. Although I did melt a grounding strap to the plug at the track running it like this lol.

Im not condoning NOT checking the tune and assuming its fine, but honestly its worth $85 to get a few pulls in with a wideband, cuz after all if you cant afford to check the tune you shouldnt be modding.

Best of luck...

 

^thank you for your imput

is getting the mrev2 along with those other mods without a tune just going overboard/dangerous? should i just do without it? i cant save up for a tune for a while, hence why im asking. thanks

 

Do the mods and drive the car. Don't be a Scardie Cat.

 

lol not everyone has money to blow on a new motor if their's craps out
