hi my 93 wrx currently has a u8 ecu chipped by scoobyclinic in it and has 271bhp would i gain anything by getting a z4?

 

unlikely

 

No

 

nope 260bhp from a z4

 

If you want more power, its time to get the wallet out and spend big money!

 

apexi power fc or simtek route but are a few quid

 

as above - no

 

thats what i was thinking! what are those esl daughter boards like? Andy Forrest charges £550+ vat for this supplied fitted and then mapped. http://www.andyforrestperformance.co.uk/57874.html

 

the ESL boards are good you can go mafless with them as well which is a bonus, IMHO i wouldn't bother with the apexi unless you find a cheap one, the going rate is around £450-500 second hand then you need to map it which is another £300, so for that money you can either have ESL fully fitted and mapped with some decent change in your pocket or spend a couple of £££ more and get the simtek fully fitted and mapped, again mafless and can have multiple maps.

 

I think thats what i shall go for
