Hey everyone, im going to be getting tuned in 2 weeks and was wondering if it will be ok to drive 200 miles(3 hours) on the stock tune with some basic mods.

Mod list:
AMSOIL cone filter
Megan downpipe
MAP Test pipe
buschur catback
Walbro 255 fuel pump

What evo do you own? I'd think you should be fine might go though gas but I'd say you'd be good.

Oh, sorry forgot to mention it's on a 2003 Evo 8.
And thanks for the fast reply

Yeah man you will be fine. Only thing I couldn't give you a for sure on is the walbro but I think I read that it isn't bad . But wait for someone else with more experience to answer that one for ya

I wouldn't worry about it.since you own an 8 ,don't forget metal evo 9 bov.good luck.

Yea the fuel pump was what I was the most unsure of.

And yea definitely need to get myself a 9 DV

You'll be fine. I went from the stock fuel pump to a DW300 pump (bigger than a walbro) And I was only about .1-.2 points richer during cruising speeds. Just don't go into boost.

Just a ?, but how would installing a wally and swapoing out the stock affect the car and why not to go into boost. More so in a negative way without a tune. Im just curious. Will it make the car go rich?

yeah, the fuel pump won't give you any issues.

You are fine. Nothing will happen with those mods.

At cruise you should not be running leaner/richer than with the OEM pump since the car is in closed loop and letting the o2 sensor do the work to maintain about 14.7 afr.

You should be perfectly fine with driving around indefinitely without a tune with the simple mods you have listed. Just know that your car will be slower than a stock Evo until you have the car tuned.

I installed a Walboro 255 on a stock tune, then drove 3 hours to get tuned. Everything was fine.

I would install the intake (unless it's just the filter and is re-using the stock tubing) and fuel pump after the trip

exhaust would be fine to drive that far

You know, I don't think it will be slower. It will surely be faster with a tune, but there will be some noticeable gains.

It will be slower because it will be running richer than it already is, it will most likely hit load cells with even less timing than before, and it will possibly hit fuel cut.
