I honestly don't know. I plan on a dyno run but last time I checked with the one AWD dyno I found so far had a 2 month waiting list. I'll have to do some more looking or go ahead and book a run in December.


rough avg is for every 1# of boost increase, one could net 15-20HP




i hope to be testing this theory on mine in near future hoping to get ~4# increase

I would say there’s quite a few variables and that would depend on the size of your engine to start with. I had 8-9 lbs to start but after cam and headers it’s 6. I am dropping 3 pulley sizes do I should be back at 9 but other variables have come into play- the cam and headers. Less restriction, more airflow, more HP.

I'm thinking the same thing ninja is thinking. I can't believe a stock non flex fuel pump can support a 2300 Whipple to the level u pushing it. What's the a/f ratios look like when u get into it?

I just realized mine is running rich at 11.3 when I get into it. I'm going to datalog it and send it to Justin. I thought my struggle to get 10mpg city was bad but 7.7..damn..I really want to hit a dyno and see where my tune is..

I need a lean cruise tune lol..

I was at 10.3 at WOT right after the cam and headers: Justin adjusted my tune so now I'm at 11 which he said is about right. He wants to see where it's at after the new pulley and said he might have to go to a 2-bar tune whatever that is, due to the limitations of my PCM. I hope it doesn't require a new fuel pump at that point but if it does, I'm going to make an access panel under the carpet in the rear. F dropping the tank.
