Best engine management on a budget? (was: Need some advice please!)
hey guys, i just purchased a 05 wrx (had 4 rsx's in the past)... its used and has a hks hipermax cbe on it. untill winter i plan on keeping the mod costs to a minimum, so i really need some advice.

hks hipermax cbe

Forget the short ram intake. Don't even think about a BOV. These are mods that make little or no power. Going catless is great for power but do you reside in a CA county that has bi-annual smog inspections? Something to consider when catless...
Cobb AccessPORT is currently the best method of engine management, IMO. It controls fuel, ignition advance, and boost in conjunction with the factory ECU. EcuTek reflash does the same but does not have the capability to store additional maps for cruise economy, race gas, high altitude, etc. like the AccessPORT.
MBC (manual boost controller) is great for modest boost gain and you can really feel the boost and torque increase much lower than factory settings but the main problem is an mbc does not provide any way to increase fueling or alter ignition advance. This means that it's possible to set the mbc for a bit too much boost increase and risk running lean and the subsequent engine damage that may result. Fuel enrichment is important for maximum power and as additional safeguard against detonation by running richer during high-boost/high load than is necessary for maximum power to utilize the cooling effect of a rich air/fuel ratio. Can't accomplish this with an mbc.

i say you get a reflashed custom tune
yes its more but i believe you get what you pay for
wingless wonder ill meet you in back and we can throw down
i do agree though
MBC = youll eventually run into major problems

heres a question: approximately what kind of horsepower numbers should i be expecting with a:
drop in filter
catless up/dp
hks cbe
cobb ap
I know its stupid to estimate numbers since all cars behave differently, but i just want the ballpark figure...

i was also wondering what modifications would yield maxium power gains with a budget of $1k...keep in mind that the car already has cbe...
also, with the accessport is it possible to turn up the boost or design some kind of your own map or is it limited to whatever cobb makes?

tune with Enginuity & ECUFlash, it'll cost you ~$90 for the Tactrix cable & less than $100 for a custom map. By far the most cost-effective form of EM available....
