Since Stage II is dead, what power mod is best?

[Jeff V]

I've been holding out for Stage II, but now that TThrift says it's not coming, I want to make the best decision based on experience that lasts (not just "I just put it on and it's GREAT" comments).

If you've had any of these on for a while, please comment!

* Stage I

* PsiFi PowerPaq

* Amx turbo/airbox pipe

* Adam's upper charge pipe

If you have these, please comment on whether the effects are worth the cost and also, do the effects last?

I have Jim's turbo/airbox pipe. When I first put it on, I noticed increased throttle response. I do not know if it has lasted or if I have gotten used to it.

What else, without risking damage to the engine?

You almost got the power of stage 2 as it is! Add a boost controller, manual or electronic, and you will surpass stage 2 levels. You don't need a map clamp since you have a PsiFi PowerPaq. If you use a Boost controller you won't need to upgrade the WGA. Get a MaxxFab or equivelent downpipe, and performance exhaust and you'll really be moving!

I live not far from Jim and I had him put the airbox and upcharge pipes in. I really believe that there is a noticeable difference. I did have problems with the upcharge couplings blowing apart, but my latest cure seems to have resolved this. I cleaned the pipe with alcohol and then applied a ring of double faced tape. The rubber coupling just fits over this and when the clamp is tightened it seems to result in a good seal that so far has stayed put after serveral WOT tests.

do your turbo back exhaust and bc

Jeff V, jim is still making the intake like you and I have. He is not Making the up charge pipe and that was what he put the factory one back,, and the other day he put his uppipe back on, but just for looks,
try not to misunderstand The Intake amx1397TTAB he still makes.

Thanks blueblue, I went to that other site and re-read and see what you mean - I misunderstood. I modified my post.

[tthrift]

a wga and a boost controller will give you more power than stage II would have given.

Jeff, I did the exhaust, intake and strut bar first, then Adam's UCP, then Stage I. The UCP gave the biggest kick in the pants. SI made everything smooth, particularly the shifts. I did install a battery disconnect so when I fill up I disconnect the ground for a few minutes. This seems to erase some bad learning over the previous 200 mi or so. [8)]

Simple mods and well past stage 2 power levels.

Thought the blow-off valve (other threads in this forum) was just a noise maker and didn't improve performance.
