S52 Suggestions, Help me!!!

[Fernflex]

I just bought an S52 with a couples of mods:

-3.5 intake
-BB Throttle body
-Big Intake boot 3-3.5
-3.5 Flow Meter
-M50 Intake Manifold
-Shrick Cams
-Injectores 24# Bosch
-Oscar Velez tuning
-VAC Motorsports Stage 2 Cylinder Head
-MLS Gasket
-Head Stud ARP2000
-Dr.Vanos kit stage1
-Header Supersprint Euro Rep.
-Clutch UUC M5
-Flywheel UUC 11.5lbs
-3.46 final drive
-Pulleys
-A/C Delete


Right now it has a tune but Im maybe changing it to another, whats the best tune out there?

Most of those mods don't have any affect on how much power you will put down. Most relevant is the VAC head which I assume is ported and the schrick cams.

I'd say between 250 and 270. Definitely no more than 270. Look up "CMT" on here or bimmerforums. He has a similarly modded S52 in an E30 and has ~270WHP, but he has sunbelt cams which are the more agressive than schrick cams. When you get to this point it mostly depends on the cams.

^Dunno who that is but i wouldnt hope for more than 250-260 on a really good day.

I've heard really good things about MarkD tunes

The car without the stage 2 head, pulleys, ac delete big tb, intake boot, stock header and the vanos damaged has a Dyno run of 245 whp.

So I have very good hopes
