Dude you could easily run the KB 6pis...hell there are people on here running the 9psi...personaly i would just get the 9....its the same thing i believe all u do is change the pulley for more boost.
Either way you'll definetly be happy w/ the outcome but you'll be twice as happy w/ the 9 # pulley

The 9# is intercooled while the 6# isn't. And of course the pulley would be different. The 6# would be simpler (is that a word?) to install, but I installed my s/c so anyone can do it. Go with the s/c that will get you the power that you need/want.

What pulley you get is your business. The non-intercooled kit is recommended safe @ 6 psi for $3799 & the intercooled kit is $4899 and recommended @ 9 psi. Keep in mind that is with 91 octane gas with Kenne Bell's tune. I would recommend if you have the extra money get the intercooler and still run it between 6-8 psi thats as safe as you can get.

If there is any chance at all that you might want more than 350hp in the future, now would be the best time to go intercooled and be prepared. If you don't intercool now and want more power in the future, it would be alot more effort/risk than just swapping on smaller pulleys. Something to think about anyway. Good luck.

That sucks. You should email or call Ken. He is usually pretty good about that stuff. He always wants to know the numbers that KB's kits put out. He isn't satisfied until you are. Maybe they could reburn your chip.

At what RPM are you hitting 303 rwhp? That's is something you should look at. When I first dynoed my car I was very dissapointed...369 rwhp. But the rev limiter kicked in @ 5300 rpm. On the second tune (second chip from KB), it was the speed limiter kicking in at 5650 rpm. With the 3rd tune (also from KB) I made 398 rwhp on the power mode and 418 rwhp on the shootout mode. It's all about the tune. Just call Ken and tell him the results and send him the dyno graph. One more thing, are you letting the car to cool off before doing the dyno pass? If not, that will also contribute to the low hp you are seeing. The KB chip will adjust the spark timing based on ECT and intake temperature. I just got a 4th chip for race only applications and will test it at the dyno next week. It should put me at 430+ rwhp02GEETEE said:

303 rwhp? Thats got to be wrong. Are the people that did the dyno competent and experienced? I would contact KB immediately and figure out what the problem is. They have great customer service. There is another board that a KB rep gets on to talk online. You might try to contact him on a forum. Someone should be able to help you with a link i just can't remember which board it was from.

Here is the link to the KB Tech forum. Post your message there and Ken will answer it in no time. http://www.modularfords.com/forums/forumdisplay.php?f=73

go to 6200 rpms and see what happens. It'll probably be about 325...BUT i still would expect a little more power than that. Maybe your timing is being retarted too much?
