You can get a boost fooler, a Banks Big Head wastegate and good programmer. An intake horn like cfm or afe would help. Vert cheap add ons for good results.

A smarty will give you the best performance on that truck. On the 03 trucks, it is so hard to beat, especially if it is all stock with no other boxes stacked or anything.

I have been VERY happy with Dr. Performance modules on my otherwise stock trucks.

They have a brass elbow with a set screw in it (boost elbow). The set screw lets you increase the boost. It changes what the wastegate sees for boost.

Without some sort of electronics package or downloader in the mix the ECM will sense an overboost condition and you will end up with less power as the ECM will defuel. This could be happening already to a small degree with the improved exhaust.

I have a used "Hot" Edge Juice w/ attitude monitor for sale. If he's interested PM me.

X2!! as far as the boost elbow, that was my first mod years ago and on my 03 I didn't have any defueling.

Smarty first. Then look for an 04.5+ turbo. That with intake/exhaust mods will get you close to 450hp at the wheels.

The 04.5 turbo will flow a lot more air than the 03 and should not give you but a tiny bit more lag. I just did this to mine and it makes a big difference and I don't notice any difference in spool up. Now I need to get it back on the dyno. Deff go with the smarty, I have a diablo preditor and it makes great power but It still lets the ecm defuel so I can,t even do a boosted launch.
