boost controller
If you are talking non electronic manual ones are pretty cheap. If you are talking electronic then as said quite a selection. AEM has one think for pretty reasonable, eboost2 is great but fairly pricey. turbosmart has their cheaper one out now seems not bad. Apexi and greedy also make some decent fairly affordable boost controllers and as said you have the ams 500 which looks pretty good just couldn't figure nice way to mount it so went with the super easy to mount in a ta eboost2.
