Towing Twins for fast spool

[Pit70RR]

I have a 99 using Mach 4's, an SPS 62 turbo and an Edge comp. The trucks runs great but if I'm not careful I can puke out some smoke (naturally). Something I want to take steps to avoid. I put on the stock HX-35 turbo for awhile as a test and it was really easy to drive without smoke. I didn't push the power levels for obvious reasons. Going back to the SPS 62 I find it doesn't spool fast enough unless plenty of care is taken and also it doesn't keep temps in check even though I've seen 56 lbs of boost.
So, I've had 3 different turbos (singles) and different injectors. I only want to do this once more. I want to go with a mild twin setup that spools as quickly as possible and will keep my current setup a little cooler. It runs up to 1450 now but I only use it in short bursts. I will sacrifice a little temp for the good spool and finally realize I need twins to hang on to my current fueling. I have no need to ever go with higher fueling.
I'm thinking about BD's Super B twin turbos but I don't know of other options or if they are using some of the newest tech or not. Opinions and info are greatly appreciated as I get ready to buy.
Motor is sound and has 85,000 original miles on it. It has a cam and studs in it. Looking more for twin options than stuff I need to do with motor. Getting a good twin setup is key. I will take other appropriate steps if necessary.

Thanks for any turbo advise.

It will be hard to prevent smoke on initial hard acceleration with such big injectors plus the Edge box. The BD twins are about the best compromises out there, but if you will be careful on takeoff, the R700 twins will keep the egts lower under full power. I tried both on my 2004 and preferred the BD R700 for that reason, but if you are mostly driving in town where there are lots of complainers about smoke, the BD towing twins will help there if you are a bit "forgetful" on takeoff and have the torque setting up there on the box.

The box spends 99% of it's time off. If it's on then I know what to expect and what I need to do. It's the everyday driving that I worry about. I don't what to leave a stop light a little fast and puke out the guy behind me. I'll just get reported for that. I want the drivability first, then lower EGT's second. Fast spool definitely first. I don't tow heavy and would never have to worry about pulling a long hill with weight and should I choose to turn the box up and play a little, it takes so little time to get up to speed that I don't worry about the EGT's much. That being said, I do want to push enough air through to be better in both places than what I have now.

Either set of BD twins should be considerably better than what you have now for spool up.

Okay, thank you for the advise!!!!

There are also several add-a-turbo kits for the hx35 if you dont want to get a whole new setup, and a little less money.
