I'm using an XFI and 50lb high Z injectors. For cold starts, I have to crank up the after start fuel curve off the top of the chart to keep it running after it fires, or it stalls out. The car runs fine, there does not appear to be any vacume leaks and the O2 readings are reasonable. Is anyone...

Anyone have a recomendation on a decent borescope? I can't go for the $3,000 variety, but I've seen several for around $500. I read that some are dark and don't work very well. If anyone has ever used one that worked reasonably, let me know.

Does anyone have or know a link where I can get the compressor maps for the Precision PT66, PT67 and PT70 turbos ?

Has anyone modified the stock exhaust manifold by welding in a flange for an external wastgate like a deltagate or racegate? Does anyone sell a replacement for the stock exhaust manifold that has an external wastgate flange already in?

Does anyone make a car cover that looks like a grand national? I've seen NASCAR car covers that are used when it's raining, and they look like the car, sponsor logo's and all.

Is anyone running a stock turbo with a good front mount intercooler, like a PT&E. What air temperatures are you reading in the upper plenum at 15 - 20 lbs of boost? I'm using a stock air temperature sensor in the upper plenum to feed an XFI, and the temperatures I'm seeing are under 100 degrees...

I want to make sure I understand how the adjustable fuel pressure regulator works before I swap out what may be a malfunctioning part. Am I correct in assuming that the fuel pressure regulator should increase the fuel pressure by the boost pressure? I have 42 psi of fuel pressure at idle with...

I'm trying to set up a 2 step rev limiter and arm the internal logger. I thought I could do this in one step. Section 24.6.2 of the manual indicates applying battery voltage to ECU Pin B19 will arm the logger and arm the Power Adder functions. The RPM is in the dashboard, and I set the logging...

Not exactly sure what whey're called. I need the plastic part that is under the headlights and above the bumper. It goes from the grill and wraps around the side. I need both left and right side.

I got a startup file from Jack Cotton with my XFI. The car would crank for about 15 seconds, start and then stall out after about 5 seconds. I increased the Cranking Fuel Table by 10% per cell to help the 15 seconds of cranking. I also increased the After Start Enrichment Table by 10% per cell...

If you got one in decent shape let me know. Zip is 07716, and I do Paypal.

I just changed from a stock converter to an original Art Carr 3500 non lockup. I replaced the lockup valve with a non-lockup valve, removed the check ball & O-ring, and used new fluid and filter. When compared to the stock converter under race conditions, the new 3500 converter seems to be...

What aftermarket ECM's have a 2 step rev limiter that can be used as a launch contoller. There was a thread about the Big Stuff 3 having a 2 step. Any others ? Bill Deliman

Does anyone make a launch controller or 2 step rev limiter for a stock ECM ?

Does anyone make a stock type exhaust manifold with a 4 bolt turbo flange, or is it better to replace both exhaust manafolds and crossover pipe with some type of header replacement ?

Does anyone make bolt on brackets for the rear point of the lower control arms for relocating the instant center? Has anyone fabricated their own ?

What is the differences between the P & Q trim. What makes the P trim better for the street and the Q trim better for a race car ?

Has anyone tried making a fuel pressure harness for recording fuel pressure in Direst Scan like the 3 bar map sensor & harness that is available for recording boost pressure using the MAT sensor?

I have swapped from a stock intercooler to a PT&E front mount, and I am getting a significant amount of knock in 2nd and 3rd gear. I was running 27-28 degrees advanced with the stock intercooler, and had to reduce to 20-21 degrees to reduce the knock. I have swapped back to the stock IC to see...

What drives the pulse that comes out the green tach wire behind the air conditioner? What drives the bar dash tach gauge, and how are they related to the RPM value that gets displayed in the ECM via a scan tool? I understand that the dash tach is unreliable. I had a VDO tach modified to work in...
