You "DO NOT NEED A MAFIA" with a 2.8 pulley with a stock blower. 1st, turn your Maf to the 10 O'clock position. 2nd, log your FPDC on your predator. Its under gas/accel (its under FP). 3rd, ask Scott for a new tune minus the mafia. 4th, get a wideband for peace of mind anyway. If Scott went over rthe tune several times, its not the tuner. They use the same base tunes as a starting point ofr every car. They meaning every mail order tuner thats worth their salt, AKA Jon Lund, Chris Johnson, James @ RWTD, Rick @ Amazon etc. If you do not get it fixed from trying what I typed above, take it to performance solutions and get a tune from Devon. He and Dan know their shit over there and give member discounts. I know that they will not stop until they figure out whats causing the problem. Gene

I didn't realize he only had a 2.8. Ditch the mafia.

Dont have a 2.8. its stock upper and 8# lower. The blower is getting ported in the next week or so and im thinking about an upper pulley along with my lower. That maf is at 10 o'clock. I would but I dont have the money right now to take it to devon.

Just drove it around the block and did a third gear pull. Started at 3500rpms, heres the data,
112 iat
3.60 maf v
36psi frp
20deg sprkadv
178% load
170f eng.
130f intake air temp.
4.62v tps
at 4000rpms the fuel was at41 with 21deg spark. 183%load.
at 5064rpms fuel was 37, 22deg and 185%
5500, 39fuel, 22deg and 181%
From what i can see on the fuel it jumps from 36-41 during the pull and 20-22deg spark.

With the 8# lower and ported blower you'll need the MAFia(or an SCT BA2400 meter). It would be great if you could log your car with a XCal2 if you know someone and send Scott the numbers of a 2000rpm to redline run.

Log these parameters (along with the A/F ratio) and get him the log:

INLET AIR TEMP (IAT1)
DOWNSTREAM AIR TEMP (IAT2)
ENGINE COOLING TEMP (ECT)
MAF COUNTS (1024 counts is 5 volts; (counts * 5) / 1024 = volts)
ENGINE SPEED
LOAD (this is the calculated load reported from the MAF)
THROTTLE POSITION ABSOLUTE (TP position in counts)
BATTERY VOLTAGE
SPARK
MBT SPARK (mean best timing spark)
PRESSURE DROP ACROSS INJECTORS
FUEL PUMP DUTY CYCLE
MAP VOLTAGE

Dont know anybody with one. It would be nice to send him my data so I can get more then 10 miles to a gallon..

I have an xcal2 with the pro racers package. It would be better if you had a wide band installed with a nine pin mini din connector so I could also log A/F. But I can see it is going PIG rich above 4K. Let me know. I live in NE Mesa.

What wideband do you recommend out of the two im looking at? I need a round gauge since i have a pillar pod for it. If I get the lm-1 I would have to add the gauge to it. There about the same price. I am down to take an adventure to get it fixed...
