6.5lbs @ WOT on a 3.4" pulley
Thats w Open cone HAI, Ported TB, Ported inlet/outled S/C, St2 InterKewler(w/ PCV notch), Ported lim, headers, catless catback, 1.9' modified rockers, zzp tune.
I think it's probably about time to drop a pulley size.

LOL, ZZP Tune.
Anywho.
3.0"...about 11psi~ at the shift.
Mods: Thrasher Cam, P&P'd Heads, Ported GenIII M90/LIM, LS1 TB setup, LQ4 MAF-Open Cone, Catless Stainless Headers, 3" Catback...idk tons of other junk.

Where is all this proof that ZZP tuning sucks?Originally Posted by bluegtp91
Anyway, on topic.
I see 27psi or so.
09-08-2011
about 9 psi peak with a 3.3
09-08-2011
Turbo's don't count...honestly since it is in the supercharged section. Also...plenty of people, including me have had issues with ZZP's box tunes...others have not. The OP has had a blown motor...if not more than once.
So...yeah.

Think I'll put a 2.5" on soon as I get the Interkewler filled.

Not sure if surius
09-08-2011
Its every bit of a L67... sorry I dont have a m90...
Anyway, I would like to see the reasoning other than "blown motor"... Is it too much timing? too lean? To "blow a motor" with a "tune" is requires some extreme mistakes.

Surius as a good custom tune to go w/ the 3.25" pulley.

I've seen 11 at the highest on the 3.4 (trying to lower it). 6.5 on the 3.8. My buddies with a gs said the highest he's ever seen his was 10.3 all stock.

i max out the MAP at 200KPA with the 3.0. so im not sure
09-08-2011
Whatever you're using to check your kPa should be showing your Boost & or MAP.

Off topic but I'd like to get a tune from locally jeremey so's I can drop pulley size.

He is a pretty damn good guy...and tunes great too.
His GenV, VS car went 12.5's all day long down at WIR a few years ago.
09-08-2011
ya i use HPT, my point is that the Map is actually Maxed out at about 5500 RPM's while shifting at 6100
HPT calculates boost at 13.5-14 PSI, but the actual number at the top of the gear is unknown
09-08-2011
N/A PSI ftw!
09-08-2011
I believe it would be 0 lol
09-08-2011
^ ^ ^ Speaks the truth right there!!!
09-08-2011
No there no blower so no boost, but there are still psi!
09-08-2011
My POS sees around 10 with a gen v on a 3.4. Because it flows like a bauce.
