Arrrggghhhh!!! Still having issues with the MAF. May need a MAF scaler instead of just a fixed voltage clamp/resister setting. Have you used PCS or Split Second?
What plugs are you using? Switched to the copper plugs 3 stages colder and it may not have been a good choice. Going back to Denso IK20s.
btw... ASP is modifying my crank pulley from 150mm to 170mm for only $250. Lee seems to be a great guy. But I won't even install this modified spare crank pulley until I get the MAF issues sorted out first.
Also just measured the pulleys on an E55K and confirmed that the SC pulley is 90mm and the crank pulley is 155mm so the drive ratio is 1.72. Therefore a 180mm modified ASP/Renntech/LET pulley achieves the same 2:1 drive ratio as a Kleemann SC pulley with a stock NA crank pulley which is 75mm.

I'm actually working jointly with Vadim and Cory. I'll give it another week before towing it to Kleemann however Kleemann never had a single one of their customers running over 9psi so my car is a first for them as well.
The good thing is that Cory assured me that they have also NEVER failed to solve custom applications with any car physically brought to them.

No Belt Slip Here
Funny Your set up & mine are real close, But I opted to stay with the OEM
(11 to 1 ) Pistons , I think you indicated you had custom (9.5 to 1) pistons.I've got a MP-112 Gen 4 , you have a IHI blower set up
When I first started to fine tune the set up I had a 2.8" / 71mm blower pulley and a 70mm idler. On the street & also on the dyno , my boost gauge would read 5.3 - 5.4 psi @ WOT and hold it there . No tapering off. The A/F ratio was perfect, 100 psi fuel pressure. Stock & recently cleaned injectors. No knock sensor voltage spikes. I then decided to go for more Boost. I called Southflordiapulley Hdqs. & got a new 2.6' / 66mm blower pulley. I lost some belt warp / Contact area . So I got a 3.55" / 90mm single bearing idler from a Mustang set up. Took 3mm off the OD, 3.42" / 87mm , as so it would clear the Pulley mounting Bracket & Thermostat hsg. Got it Hard coated anodized. Now I'm at 6.6 Psi At WOT . I have a little more belt contact patch, also. If this works out I'm going to have a Double ceramic bearing pulley made. There still no indicate of slip with the stock or with my new setup. My car runs great

Just heard from Lee at ASP that he accidentally put an 8rib outer ring on my stock pulley!!! Should I accept that or make him redo it?

I'm getting my wheels refinished for $200 per wheel (grinded, polished, and clear coated) before putting on the KMACs and SpeedyBenz toe end-links tomorrow. Then final alignment and dyno on Friday. Next week the 170mm crank pulley will be ready and I will have Vadim re-dyno it.

Make him redo it, unless you plan on switching all your pulleys to 8 rib

Sorry about so much detail but I just can't wait any longer for the final test results on the dyno and track. btw..I paid him $350 to install my 5-gal trunk resevoir. Is that a fair price? Final alignment and dyno tomorrow!!
As for Lee, I said OK for now since the extra two ribs won't make any real functional difference other than looking funny.

Sincerely hope your dyno goes well tomorrow, but forgive me when I say "I'll believe it when I see it."
Best of luck.

Dyno'd yesterday but had a problem. I will need a programmable/digital MAF in order to get the ECU to read and recognize the increased air flow to trigger the injectors to open. Right now it's either too rich on the bottom and too lean on top or if we adjust the resister then it's too lean on the bottom and too rich on the top.
The current resister adjustment narrowed the band width too much. Quoted cost was $1200-$1500. Then if it goes over 5 volts I will need a larger MAF housing like the ABACO product as well. Gary feels that the stock injectors and pump should be OK unless I add a much larger crank pulley.
I am now working jointly with Vadim and his partner Gary....

btw...Dyno was aborted before max RPM was attained due to dangerously lean condition up top. Prelim was 460rwhp at 4000rpm I think. Still waiting for the chart to be emailed to me but it's really meaningless until I get it to run right.

Hmmm, it sounds like Vadim is trying to adjust fuel by just messing with the MAF resistor. That won't work. I suggest you get a tuner to custom tune your car on the dyno and add/take out fuel where its needed across the rpm band. You're almost there, just need a tuner! My car should be running 65mm pulley soon. Within the next 2 weeks. Eurocharged will be tuning it again on Feb. 6th hopefully if nothing weird pops up. I am planning an increase of belt wrap now but not sure which route to take yet. I will let you know how it goes.
Btw, 460whp at 4k rpm is alot!
