What HP numbers do you guys see with mild injectors and timing only boxes?

I was on the stock HY-35 turbo with a j-hook, 29lbs of boost. The HX-35 can go a few lbs more on boost and still be efficient, but I still wouldn't go much past a level 1 injector if you are going to tow 12k lbs. That is a lot to tow. If you want more power go with a light injector and a bigger "adjustable" box. That way you can turn it up for fun, and down to tow. I eventually dumped my VA for a Edge Comp and am much happier. I can still turn it down to tow and not worry about my EGTs.

Good advice, guys, thanks.
Hell, I'd be happy if I could hold 3rd at 55-60 mph in lock-up taking the long freeway grades. 12k is alot but with those 60-75 hp injectors, do you think they will solve my delima?

Muddy, do you know why the ETH trucks run hotter? Just curious.
Thx.

i dont know why the eth trucks ran that much hotter to be honest. 10 hp and 45 tq more than the etc trucks. not much more but sure a lot of heat. compresion ratio was differnt. programing of the stock ecm was different. injectors stock were actually slightly smaller.
i know that some had prefered to go the etc trucks for bombing due to less egt.
mikey, imo the approx 75 hp inj with a timing box would be best for your 99 for an all around towing rig with a stock hx35 keeping manageable egt. my combo on my 98.5 was just right for me.

compression ratio 16.3 etc to the eth 17. the factory boost setting for the etc motor was 20.8 psi in 01 or 17.7-18.2psi for 98.5-00. The eth motor was set at 26 psi. also the injectors on your 98.5 should of been rated for 10hp more than your 02. etc is 235 eth 245. So if you bought the same injectors the trucks should make same power but the 98.5 needed 10hp more.
