Hey guys, Im posting for a friend. He has an 03 MSP with intake/full exhaust/FMIC. Boost is still stock, hasnt turned it up yet. He just bought an AFC but the more I do searches the more I find people saying it will not work. Which is kinda weird but oh well.

So, to date, is the Apexi AFC definitely a no-go for the MSP? Also, what can my friend use to tune the car? Emanage? Dont tell me standalone please, hes tight on cash. Looking to spend 250-450ish.

Also what can he turn the boost up to safely w/o hurting anything with his current mods. I believe he is running 5.5 right now (stock). Thanks for the input.
 
The only AFC that works with our car is the Split Second unit sold by DSMConvert on this board. He could also use an Emanage, Unichip, MPI Tuner, Haltech 10f (?) or E6X, or go stand alone.

The Split Second AFC is the only one that falls in your budget.

I wouldn't feel comfortable boosting over 10psi on stock internals. There are people that have run higher, but they're retarding their timing too and the Split Second doesn't do that.
 
g

i run 9 psi when not cold out as long as he freed up the exhaust he should be fine i really think anyone of you guys trying to turn up the boost should invest in a wideband o2 and then you will know what the car is doing My car has went up to 12.3 before on a/f ratio when cold but it also has stayed pig rich when hot at 9 1/2 psi all the way to redline anyway yea go for 8 or 9 just dont boost in higher gears
 
Yeah he has exhaust, full, and FMIC, intake.

Whatever fuel tuning device he gets would be tuned on the dyno, that was the plan.
 
yep with his budget I would go for the airflow logistics AFC sold by DSM its a great product!!

Haha that reminds me. Is there any vendors who make 02 housings with dump tubes like they do for the DSMs and such.

Is there a website for this DSMConvert AFC so I can check it out? Also, what is this AFC thing? Is it liek an Apexi AFC?? Is it a reflash. I searched but came up with garbage like usual! Thanks!
