Ya man James Parker AKA Bubba AKA RWTD use to tune my 02 AMOF
REAL NICE GUY, REAL GOOD TUNER
Def the Diablo Man..... Good Choice and Good Luck

Ask him about Rob from NY and Fuel Filters, he was the one who convinced me to cut mine open after the truck leaned out and burnt three plugs at the track when it was DAM NEAR BRAND NEW. I listened to him and this is what I found on a Filter with 6,000 miles when the L had 6,000 miles on it
(it actually clogged at 3500 miles thats when the trouble started)



I changed the filter and plugs, went back to LI Motorsports the following weekend and ran a 12.8 on his tune with F-1's no traction bars open filter and 4lb lower pulley, NOTHING ELSE. Back in 02 that was a great Et for no mods, just a 4lb pulley, and no bars slicks or other mods...

 

You'll be glad once you get it dialed in.. Theres nothing like a good custom tune. Even though your mods are low, they wont benefit that much with a canned tune. I've heard good things about RWTD mail order tunes. You should see a big power increase.. Make sure you catch it on a KODAK/Video moment. Let us know how it turns out.

 

This is the Air/fuel most tuners recommend for a #4 pulley. I have had tunes and have specifically asked the question of air/fuel to both JDM & RWTD and they have said and provided tunes in the 12.0-12.5 range for a 4lb pulley. Anything more is pig rich and creates a power loss. It's when you start using a #6 or more that you need to start dumping in lots of fuel for cooling and more safety factor.

 

It would depend when you asked that question, years ago a typical dyno graph would actually look like DA's, meaning it would start off lean and then go under 12 somewhere before say 3500 - 4000 RPM
This one is a little extreme, it's my old 02 stock Block on Nitrous

Sal wasnt the tuner, it was just his dyno.
Today that would be a wacky Dyno Graph no doubt, back then it wasnt that unusual

Today most Tuners Flat line them from start to finish UNDER 12.0 (usually @ 11.8) If you go over 12 you really need to be running C-16 to be safe and most wont even go over 12 for a race tune (like the orig JDM Graph I posted)

 

Yeah, most of my AF line is below 12 if you notice on my JDM tune.

 

I cut my last fuel filter open, and it was pretty clogged up! I wonder what this latest one will look like
