you can run cobb E30 map which is about 5 gallon E85 rest is 91 or 93 for half and half you have to get it pro tuned for the max performance and for over E40 you will have to upgrade your lpfp just to be safe. I am running cobb e30 map daily and I'd say I am happy with the power but everybody will say go with JB4 either choice you will not regret it. good luck bro..

cobb released e30 map long lime ago which is I am running daily but you need to be fbo you said you'll be running down pipe all you need is 5 or 7'' upgraded intercooler and intake. to run e40 which is 7 gallons e85 and rest is 91 or 93 oct pro tuning freaks has a custom map for it I think is $250 for an e-tune. Cobb is way easier to install..

my inut why go cobb, there specialty is Subaru and Evos

Jb4 is all about Bmw and BMW only, Terry knows his E90s ,

sure Cobb is a plug and play , but will not give you as many options

as JB4, I switched over from cobb to JB4 and its the best Mod i invested.

coming from the Subaru scene im a ex STI owner stick to jb4

you will love it !


currently running

VRSF DP
7" VRSF FMIC
ER Chargepipe
VanguardV2 exhaust


soon

RB turbo
Meth
fuel pump and injectors
