Ok, I am not trying to start a jb4 vs procede topic, but i am in need of factual information. I do not want the cobb flash as i will only be running a few bolt ons and from the dynos i have seen jb4 and procede put down more power with simple bolt ons and have many extra options that cobb. With that being said i am not sure what to get. I have been leaning twords procede for the possibiity of getting vishnu's flex fuel kit down the road. If you guys could point out the differences between the procede rev3 v5 and jb4 g5 iso (other than the $300 price difference) that would be great. From viewing each site it is difficult to understand exactly what you are getting.

None of these tunes put down that much more power than the others, unless you start adding things like meth and ethanol. And even with ethanol, cobb has maps as do jb4 and procede.

Jb4 and cobb seem most popular on this site

PM me and I'll give you some tips. Bought them both and currently own only one of them.

its a great thread to see the differences. watch videos on how they are used, power level should be similar so dont expect one to be way better then the other even though it might spark a argument. the price difference usually does it for most people, but vishnu has a cheaper procede out now.

look into features of both. I have been using a JB ever since i got the car and i would recommend it.

or try both and return one. im sure they have a return policy

Does jb4 have a wastegate rattle fix similar to procede?

Yes.

A nice procede fact is that you do not have to buy a downpipe fix. It's built in. Also, the vin lock is to be removed later this month with new maps. Stay tuned.
