what do you guys feel is the best tuner for a ls1?is one better than another for power?what all can you adjust with them?thanks

 

HP tuners is by far the best for any GM V8..tuning capability is limitless

 

I agree on the HP tuner. If you can find someone with an HP, then have them do a tune. You my not gain the advantages from a tune based on many factors. An LS1 with 150k miles may not gain from a tune. Would need to know what kind of condition your LS1 is in. To really find results you need to baseline dyno it. I'm not sure the seat of the pants dyno will provide good numbers. Some thoughts B4 you spend the money.

 

Agreed! And if you don't want that for some reason all I can say is....

 

I have a diablo predator and i saw a big difference with just a diablo preset tune. You can custom tune or just use the preset ones. My SS is a a4 and it adjusted shift points and shift pressure and it was a huge difference all around it shifts nice and firm, that with the 373's woke up my car big time.

 

Oh yeah, 373s help out alot! Blue_thunder01 has 410s! That thing is freakin nasty! I'm gonna go with 391s when I get the money! I do alot of Highway driving though. Blue-thunder01 lives like a mile from his work so it doesn't really bother him.

 

Your M6 should do just fine with 410s. Probably be equal to my A4 with 373s. At 70 im at 2500 rpms. I didnt think it was too bad, it responds great at 60. I do miss my 95 z with the M6 though. I put the gears after my diablo and just stock with the diablo was still a nice difference.

 

At 2000rpm I'm at 90 in 6th. But I have stock gears. I've driven blue_thunder01s car and he's told me before but I can't remember what he's running at 2000rpm. It's somewhere around 70 or 80 but I can't remember.

 

Damn!! Lol. What gears do you have stock 273?? Before the gear change it had stock 323 at 70 rpms would be right at 2000. So it jumped a bit but its ok on cruise she breathes well. I think my 95 z in 6th at 70 i would be at like 1500 or so cant remember i believe it had 323s im not sure. Fun car that one was built nice motor wise. Good times. Lol

 

Mine are 340somthings. I can't remember the last number. You can look on the inside of your door and there will be a sticker with a whole bunch of numbers on it. Those numbers are alll of the options/specs your car has from the factory. I don't remember where we looked it up but when me and blue_thunder01 looked it up it said I have 34somthings.
