'03 turbo w/ batmowheel VS Powermax?

[BlkSC]

I have 190cc injectors w/ 75% nozzles from Warren Diesel on the way as well as an Airdog II DF-165. I currently have the factory '03 turbo on my truck and I've been reading that some people don't feel like the Powermax offers much over the one I have on my truck. Any truth to this?

190/75's are way too much injector for a stock turbo even with a Batmowheel. I have a Pmax/Bwheel with 175's and working with 4 well known tuners have not been able to get an acceptably clean street tune and my egt's are unacceptably high. You have a tough combo to tune there.

It does flow more air than the stocker. It just runs out of air on the top end like like the stocker. You could get a batmowheel for the pmax and have more flow. Not sure if the wheel helps out with top end flow though.

If I were you, I would try an s362 or s364 non vgt turbo with diverter valve. I have a bullseye batmowheel s364 in a compound setup and it spins up very fast. The pmax is the easy way to go, but has its limitations.

i'd say stick with the 03 turbo, possibly throw in a batmowheel. the money spent on a powermax in my opinion isnt worth it. Or do what kdogg said and try a smaller non vgt to get better results... albeit more expensive

Im thining about going with 175's with a stock 03. I do pull stuff but not very often at all 2-3 times a year...Do you think that would be too hot? Should i go with 155's? I would really like more power because i mainly just daily drive this truck with no load!

With a stock turbo I wouldn't go bigger than 155's based on my experience with my current setup.

I'm sure I can get mine where I want it but it is looking like it'll take live tuning to do it.

Ok, i dont care too much about the smoke i understand that all comes with the bigger sticks, but i just do not want to melt down! Sometime in the future i will probably go with a bigger non-vgt charger and i just dont want to get the 155's and then regret not getting the 175's. Too many options!

IMO 190s are too big for the Powermax... That's what I have and there is zero turbo lag, but it gets hot and smokey really quick. The pmax runs out of air at the top end, and it doesn't pull any harder at WOT than at about 3/4 throttle. That said, the Powermax was a huge improvement over the stock 03 turbo, but it is still not enough. I am looking to get a nonVGT with a diverter valve and I would recommend you do the same.

I beat a friend of mine in a race, he has with 155's and a powermax with IDP tunes in my truck with 190's and an 03 turbo TSD tunes and my truck smokes less... food for thought.

I would honestly recommend 190/75s, perfectly street-able and you can easily manage egts. I tow myself around 8-9k very frequently in the spring/summer with lawn mowers etc and on a street tune its perfectly fine and I live in the hills.

190cc/75% with a gates 62/65/70 is an AWESOME combo.

You could wait and get a rcd 62 or 64 turbo kit. I believe it has everything needed to hook everything up. I used their pedestal for my 64mm and it fit perfectly. don't panic if you have read about rcd's troubles, that's with their injectors, their turbo's are pretty much the same as anyone else's.

I had a pmax and 175/100's on my truck before the compound setup went on. I had it live tuned and it ran super, but the tuner had to pull back a good bit of fuel to keep from pegging egt's. The tow tune would peg at 1350 and the street tune would go 1600 easily. I had and still have a few airflow improvements as well.
