Got a new to me envoy xl a week ago 106,000ish miles, 1st 5.3/Ls based motor (yes I know it's techinacally an lh6) Sending my pcm & tcm out today or tommorrow to Jeremey and I'm figuring on dod delete, vats delete, firm up shifts, advance timing and tq management delete.
Anything else anyone recommends and maybe a brief explanation on why?
Also looking to do LT headers, catless y, mandrel catback, mild cam maybe torque or some mild truck cam with around 212/218 haven't decided so kinda taking my time also figuring springs, lifters/trays, gear, chain/dogbone tensioner, hardened pushrods see attachment of cart pic, probably do the pickup tube o ring, trans cooler still debating other mods, definitely replace the cam cover plate gasket while I'm in there and I do know of a rolled tbss near me that I'd love to score the intake mani/throttle body off of. Ideally I think my primary mod goals are 400hp/400tq (300whp) 1st than go from there but I do have some lifter noise and low oil pressure so will be getting that taken care of asap only drove it maybe 20 minutes it was supposedly a non runner with rat chewed wiring so I spliced that after making a partial trade deal for it doing electrical on sellers house plus throwing some cash. Soon as I rev it and oil pressure goes up the noise goes away, so it's not that bad yet imo plus I wanna cam it anyway so lifters are a good idea while in there also getting caged bearing preassembled rocker arm/trunion I'm sure I'll add to my cart as I go. I'm guessing a few months from cam:30 n headers so figured I'd send pcm back when that time comes for o2 stuff if spark plug defoulers don't work on LS stuff 🤷 and cam tuning, so anyway back on topic, any recommendations welcome far as tuning or mods in general! Figuring I'll try to keep the 4l60e long as possible but will also be looking into 4l80 swap and maybe tbss rear end if and when the time comes 😋 just in case... but I'm much more of a stereo nut that speed demon. also my name's Tom in case people are into intro's here 🤙been a member of offroadtb and trailvoy but never really post just super excited to get an ls money started (been looking for months at 2500s with lq4 ect 2500 burbans just couldn't spring what they want here and scored this for around $1,000 and a days work so looking forward to dumping my 4.2 swb and burning the money, thus tq management delete while braking 🤣) sorry adhd moments hold me captive 🤦♂️middle age says it's time for a budget boosted car eventually 🙃
