For fueling on my DD 99 I run a set of extrude honed, sac, 7x10 RV275's from St.Joe's on an other wise mostly stock 24v. I have been very happy with these injectors & there "all around" capabilities. With an S.O. Vp & Edge JwA on stock or level 1 there is little to no smoke. Level 2 is great for towng, smoke is totally controllable & egt's typically never exceed 1050-1150. 3-4 are great for DD but can get warm & smokey when towing. I really can't cant comment on high rpm capabilities as it's just not set up for that yet. It's got a NV4500, factory 3.55's, & run 315's so it's geared fairly tall but it is fairly light for a ECLB with a Hillsboro aluminum flat bed. Usually see 15-17.5mpg. Idle is clean so long as it's not real cold & they have been great for towing & DD. The truck feels nice and snappy. Egt's are typically 750ish* cruising unloaded & and 950-1050 when towing. I can only recall seeing 1250* one time while towing even with the old HX-35 & I usually didn't see over 1150 at any given time when towing. Overall has been a nice cool running Setup so far. One of the cool things I've noticed is that the truck can be driven virtually smoke free when romping set on the lower levels or even when set on kill just have to take a little more time. When cranked up & horsing around they kind of go Dr.Jeckel/Mr. Hyde and can really black things out. The fuel is really there and truck is currently getting air/motor upgrades. Set at 5 or 6 the truck runs like a s.o.b up to 3250-3450 but by then it's time to slow the f* down. :hehe: Have seen up to 1250-1300* momentary when horsing around. I know the VP has it's quirks but I have really enjoyed this setups adjustability of power and the ability to limit smoke to appropriate levels. Sorry for the long winded post. Just my $.02, hope it helps man.
