not enough power

Hi guys I'm looking for some input on my buddys truck to get more power.
The truck is a 97 f450 5spd Right now the mods are:

-Edge evolution programer set on extreme
-6.0 intercooler with early 99 wastegated turbo.
-cold air intake and 4" exhaust.
-bd x-monitor pyro/boost
-luk SMF flywheel/clutch upgrade

So with the wastegate disconnected and held shut we could only manage about 22psi boost and Egt's were about 950.There wasn't too much smoke but it feels under powered.We then decided run it without the intercooler by simply putting the orignal intake Y peice back in.I thought for sure that we'd see a big increase in boost and EGT's.We took it for a drive and saw Egt's stay about the same and boost went to 27 max and there was less smoke and a little more power.

It seems quite clear that this truck doesn't need an intercooler now.

Is this engine just suffering from lack of fuel? It seems like the extreme program is not so extreme like we thought it would be.Edge says that it can give a 100 hp increase but it seems like we are getting about 70 hp increase.

Should we look at getting a different tuner/chip or an injector upgrade?

This truck is used for towing so we don't want it to be smoking too much and the other thing is we don't want to have to much power to slip the luk clutch.

I don't think he'd mind upgrading the clutch if we needed to.He's almost thinking about putting a cummins in there if its going to take alot more to make this truck perform.

Thanks for taking the time to read through this.Any suggestions or input would be greatly appreciated.

the edge will only add about 60 hp tops.

When my truck was stock with just intake, exhaust, and TS 6 position chip i dyno'd 217 hp and 444 ft/lbs of Torque.

With stage 1 injectors, custom tuned chip you could break 300 hp easy. It will feel like you are driving a whole new truck. I would definitely run the intercooler with the stage 1's. You have to remember, more boost doesnt mean more HP. Your stock turbo performs best under 25 psi of boost, with stage 1's you will be able to hit 30 psi easy, but i wouldn't go much over that. Also your clutch should be able to hold up to the HP.

Thanks for all the input guys.If he could only afford to do one thing at a time which should he do first ? stage 1's or Custom chip?

Would the stage 1's only work at 50 % with the edge? Is this why you'd really need to do both to make decent power?

Cannot use larger Inj's with a edge..As good as a custom chip is you are not going to see 50-60HP with any chip. To bad you switched to a SD turbo..you had better options before. Stage 1's and a TS chip with custom tunes, a WW to help surge on that turbo would be my first change.
