Went to the dyno shop yesterday:

269.4 RWHP
324.7 ft lbs torque

This is on a 4X4 with an auto running 91 octane pump gas with no additives. Run sheet is on the webshots link below if you're interested. Before you ask, the dip @ 4700 RPM was the knock sensor saying hello then the ECU adding timing back in sloppily. Knock sensor just letting me know that I needed to go a size larger with my water injection nozzle. Let me know what you think.

Very impresive! Hey how did you decided on that WI nozzle in the first place? I am about to install mine and don't know which nozzle I should try first and how to inspect if it is the right one.

Also did you notice a big difference in shifting after the IPT valvebody? How much did it cost? Thanks

Thanks. Gadget suggested the .8 nozzle in his install instructions. After the valvebody install it was like a different tranny. Much firmer and quicker shifts.
I can chirp the tires from first to second on a regular basis. I highly recommend you think seriously about getting this done. John at IPT did a great job for me and his customer service is great. That was a good thing because for me to rip the valve body out of my new truck with less than 2000 miles on it and putting it in the mail to send it across the country and back again was damn scary! I paid 475.00 plus shipping.

On that particular dyno run, I pulled the cats and put in a test pipe and went to a 2.0" pulley. I didn't change the fuel map from the 2.2 so the extra boost set off the knock sensor. If I had upped the water nozzle to a .9 that would not have happened. (I think)

Hey thanks, that is really good info. I do plan on doing the valvebody soon. I just haven't found a good time to take it off. I was hesitant to do so because like you I have an 04 and it will pretty much void my tranny warranty.

Did you get the TB spacer to put the WI nozzle in? If so wern't the bolts(2 bottom) too short? My TB is slightly different from earlier models I am assuming your is too. The earlier ones appeared to have all 4 bolts of equal length. Mine come with the 2 bottom longer.

Yes the bottom bolts were too short. Gadget had no 04 truck at his disposal to work from and I guess Toyota changed throttle bodies midstream. Gadget is aware and is making changes for the 04.

Thanks for the heads up. Hey show off...you should start upgrading your suspension (coilovers) so you can rail those corner. :D

No, I probably am going to leave my TRD package alone for now. Believe it or not I bought this truck to use as a "Tow Dingy" behind my motorhome. Alot more fun than some damn Saturn these RVers usually tow.

TRD coils and struts are too soft. I couldn't believe how hard I rail turns now with my DR coilovers on the road even with 2'' lift I can way corner better than a stock truck. Just letting you know my experience.
